This technological 

revolution isn’t just 

for urbanites.” 

For the 80-plus per cent of North Americans who reside in urban 

areas, it is easy to believe that technology is reserved only for 

those who live in the city. Our city lives, after all, are immersed in 

technology. We’re connected by smartphones, transported along 

our roads by vehicles with sophisticated computer systems, and we 

rely on myriad apps that automate virtually everything we do. This 

technological revolution isn’t just for urbanites, however. Technology 

in the field of agriculture is also moving swiftly forward. While the 

modern farmer still maintains his or her stereotypical elements —they 

still rise at ungodly hours—the tools they use are as sophisticated 

as any employed in the city. In this issue of Maximum Yield, we 

explore the changing face of agriculture and its emerging technology. 

Cory Hughes provides us with a 10,000-foot view some of the new 

advancements in traditional agriculture, including automated 

agriculture, artificial intelligence, and the rise of agbots. Meanwhile, 

Tim Jennings takes us closer with insight on amazing technology 

like micro drone pollinators, also known as RoboBees. These smart 

little robots are the result of collaboration by some seriously smart 

propellerheads who are looking way into agriculture’s future. Both 

features are worth a read. Of course, not everybody is a techie. For 

many, the pursuit of growing still means getting their hands dirty in 

some soil or maintaining an indoor hydro system. We’ve got those 

covered, too, with Sara Elliott’s article on the delightfully simple 

but effective herb spiral or Frank Rauscher’s comparison between 

deep water and NTF systems. No matter where you live, the 

city or country, the team here at Maximum Yield wishes 

you a happy new year and success in all your growing 

pursuits. If you have any questions 

or comments, feel free to e-mail us

Q 

Hello, 

I grew cucumbers the last two winters in my hydroponic set-up and noticed that 

the flavor more resembled water than cucumber. I suspect the temperature in 

my growing area is not warm enough. It’s around 75˚F. Any suggestions? 

Thanks, 

Scott 

A 

Hello Scott, 

Unlike tomato fruit, cucumbers don’t tend to 

develop a particularly strong flavor: however, 

they shouldn’t taste like water. There can be a 

number of causes for a lack of that distinctive 

cucumber-ness, and they are largely related 

to genetic and/or growing conditions and 

nutrition. Firstly, flavor strength—which is 

made up of sugars, acids, volatiles, and other 

compounds—varies somewhat between the 

different types of cucumbers. Older, open 

pollinated varieties and types tend to have 

a stronger flavor, but are prone to bitterness. 

Greenhouse, hydroponic hybrids, on the other 

hand, are milder in flavor, unlikely to become 

bitter, and higher yielding. 

Growing environment also plays a role 

in the development of flavor compounds. 

A temperature around 75˚F is fine (optimal 

temperatures are 72-82˚F) unless the nights are 

much colder than this. 

Nutrients play a significant part in cucumber 

quality, too, as the plant has a high requirement 

for potassium (K) in the fruiting stages. It’s 

recommended to use a K booster or high-K 

fruiting formulation during fruit development, 

along with some additional calcium. Also, run 

a higher EC in winter (around two to 2.2). 

Some growers have found the addition 

of silicon to the nutrient solution 

assists flavor and fruit quality 

in cucumbers, too. However, 

silicon supplements 

can push the pH of the 

nutrient solution up, so that 

requires extra monitoring 

and adjustment. 

Avoiding overwatering and saturation 

of the growing medium also 

assists with improving compositional 

fruit quality and flavor strength. Light 

may be another issue; cucumbers 

need a lot of light, and if sufficient 

light is not present for maximum 

photosynthesis, the fruit won’t get 

enough sugars. This can result in 

poor flavor. Similarly, if the plants are 

carrying a high fruit load, then the 

supply of sugars (assimilate) allotted 

to each individual fruit is restricted. In 

this case, pruning fruitlets to reduce 

numbers may be beneficial. 

Finally, the stage at which the 

cucumber fruit are harvested and 

how they might be stored also plays 

a role with flavor. Cucumbers that 

are harvested fairly immature tend to 

have a milder, less developed flavor, 

while those that are over mature 

develop a watery, sometimes bitter 

flavor. Once harvested, cucumbers 

should be eaten as soon as possible. 

They do store well under refrigeration 

wrapped in plastic, but if storage is 

more than a couple of days, this does 

reduce compositional quality. The 

cool conditions in the refrigerator are 

likely to effect volatiles that contribute 

significantly to that cucumber flavor. 

Hope that helps, and good luck with 

the next crop. 

Kind regards,

YK? 

POTASSIUM (K) 

Potassium is needed for controlling both water uptake and the process allowing plants to harness energy from the 

sun (photosynthesis). Potassium promotes flowering, fruiting, and general hardiness. In hydroponics and in light, 

sandy or chalky soils potassium is easily washed away. Clay soils, by contrast, hold potassium within their structure.

Philly to Get First-ever Passive Solar Greenhouse 

Philadelphia will soon be getting its very first passive solar greenhouse 

thanks to a $5,000 grant from the Whole Cities Foundation. Led 

by the non-profit Urbanstead, a community farming and youth 

education organization, the project will produce a sustainable 

greenhouse that requires no energy source other than the sun 

to function. The Whole Cities Foundation, run by Whole Foods Market, 

provided the funding through its Community First Grant Program. This year’s 

grantees include community gardens, urban farms, mobile markets, and pop-up 

produce stands. For Urbanstead, the project will directly translate into increased food 

access for Philadelphia. “This will allow us to extend our growing season all year round, which is 

very exciting,” says Urbanstead spokesperson Yoni Kroll. “While we occupy only a small part of the 

overall urban farming community in Philadelphia, we hope this will be an inspiration for other groups.”

GROWING TIPS, NEWS, AND TRIVIA 

Spinach Bomb Squad 

By embedding leaves with carbon nanotubes, MIT engineers have transformed 

spinach plants into sensors that can detect explosives and wirelessly relay 

that information to a handheld device similar to a smartphone. “The goal 

of plant nanobionics is to introduce nanoparticles into the plant to give it 

non-native functions,” says Michael Strano, the Carbon P. Dubbs professor 

of chemical engineering at MIT and the leader of the research team. In this 

case, the plants were designed to detect chemical compounds known as 

nitroaromatics, which are often used in landmines and other explosives. 

When one of these chemicals is present in the groundwater sampled 

naturally by the plant, carbon nanotubes embedded in the plant leaves emit a 

fluorescent signal that can be read with an infrared camera attached to a small 

computer. “This is a novel demonstration of how we have overcome the plant/ 

human communication barrier,” says Strano, who believes plant power could also 

be harnessed to warn of pollutants and environmental conditions such as drought.

Mangos May Help Modulate High-fat Diet 

Research published in the Journal of Nutrition has for the first time documented the potential effects 

of mango consumption on gut microbiota of mice. When samples were compared from the 

beginning to the end of the study period, mango supplementation was found to prevent 

the loss of beneficial gut bacteria often induced by a high-fat diet. This is an important 

finding as specific bacteria in the intestinal tract may play a role in obesity and obesityrelated 

complications, such as Type 2 diabetes. In this study, published in the Journal 

of Nutrition, 60 male mice were assigned to one of four dietary treatment 

groups for 12 weeks—control (with 10 per cent of calories 

from fat), high fat (with 60 per cent calories from 

fat), or high fat with one per cent or 

10 per cent mango. All high-fat diets 

had similar macronutrient, calcium, 

phosphorus, and fiber content.

USDA Invests in Aquaculture Research 

The US Department of Agriculture’s National Institute of Food and 

Agriculture has announced four grants totaling $1.2 million to support 

the development of environmentally and economically sustainable 

aquaculture in the United States. These awards were made through the 

Aquaculture Research Program authorized by the Competitive, Special, 

and Facilities Research Grants Act, administered by NIFA. “In 2015, 

Americans spent $96 billion on seafood, but only a small portion of that 

was produced by US aquaculture,” says NIFA director Sonny Ramaswamy. 

“To meet the growing demand for this healthy source of protein, NIFA investments 

are helping enhance US aquaculture production to promote both economic 

opportunities and a safe, reliable domestic seafood source.” 2016 awards went to 

Michigan State University ($307,869); Virginia Tech ($275,887); Auburn University 

($326,250); and The Research Foundation of State University New York ($326,963).

Milwaukee Will Have Largest Urban 

Organic Fruit Orchard in US 

Milwaukee County will soon be home to the largest urban 

organic fruit orchard in the US. Wisconsin Public Radio 

reports the first of 3,000 fruit trees, 4,000 asparagus 

plants, and more than 16,000 strawberry plants were 

planted recently at the orchard in Oak Creek, as part of 

the county’s Sowing, Empowering, and Eliminating Food 

Deserts Initiative. Milwaukee County Supervisor Marina 

Dimitrijevic began the program in 2015. She says the orchard 

could serve as a learning opportunity about the need for 

access to healthy food options. Dimitrijevic says the benefits of 

the locally grown food are worth the $100,000 investment from 

the county. Milwaukee County Supervisor, Steve Taylor, 

says the produce will go to those in need, with schools and 

low-income residents getting access first.

Chemical Origami Yields New Plant Compounds 

Plants produce countless kinds of compounds, also known as natural 

products. A study published in Proceedings of the National Academy 

of Sciences focuses on triterpenes, a large group of plant natural 

products with a range of biological functions and potential 

uses in medicine and other fields. The researchers report that 

changing the genetic code for one amino acid in a plant begins 

a process that alters the shape and function of an enzyme, which 

changes the folding of the chemical precursor. The technique is like 

chemical origami and produces a new natural product with a variety of 

potential uses. “Changing or modifying plants is not a new concept,” says 

study co-author Robert Minto from Indiana University. “In the PNAS study, we 

changed a single amino acid in an enzyme from the root tip of the oat plant to 

alter the function of a single enzyme. Being able to go in and do that directly is 

much more efficient than cross-breeding plants.”

Coffee Cherry Pulp Converts to Nutritious Flour 

Billions of pounds of coffee cherry pulp are produced each year as a byproduct of the global coffee industry, which 

often goes to waste, but one enterprising company is converting some of that into a flour that can be used as a 

nutritious alternative to grain-based flours. The aptly named Coffee Flour only has a tiny bit of caffeine and does 

not taste like coffee. The company is currently running coffee waste-to-flour operations in Hawaii, Nicaragua, 

Guatemala, Mexico, and Vietnam. The company’s founder, Dan Belliveau, refers to its product as a “found 

food” that can reduce waste while also generating more revenue for the growers. “The coffee cherry 

waste stream has historically been something that had to be dealt with, as it takes a significant amount 

of property to store coffee cherry pulp throughout harvest time,” he says. Coffee Flour is advertised as 

containing more iron than spinach and more fiber than whole grain wheat flour.

National Organics Standards Board 

Can’t Decide if Hydroponics is Organic 

At its annual meeting in mid-November, the National Organic Standards 

Board voted 10-4 to send the decision of whether hydroponic-grown 

produce should be certified as organic back to committee. This move 

maintained the status quo of hydroponic operations being able to apply 

for organic certification. The questions the NOSB continues to debate 

is if organic farming requires soil. Traditional organic farmers 

say fostering fertile soil is a vital component to the organic 

definition, while hydroponic farmers argue that they simply 

recreate the biological processes found in fertile soil in 

different media. Mexico, Canada, Japan, New Zealand, 

Holland, England, Germany, Italy, France, Spain, and 

17 other European countries all prohibit the sale of 

hydroponic produce as organic. However, many 

hydroponic growers in Mexico, Canada, and Holland 

sell their hydroponic produce as certified organic in the 

United States thanks to their ambiguous policies.

University of Iowa Updates 

Greenhouse with Hydroponic System 

The greenhouse on top of the University of Iowa Biology Building 

East is getting a much-needed update. The greenhouse’s new 

hydroponic system will allow for larger plants and a larger variety of 

produce for the UI Gardeners, who help run the greenhouse. “The 

new system is much deeper and you can have things like tomato, 

watermelon, squash, peppers—all kinds of stuff—because it allows 

the roots to grow,” says Sophia Coker Gunnink, co-president of 

the UI Gardeners. The group is hoping to use this new excess 

of fresh food in its free produce program and as consistent 

donations to non-profit centers. Although the greenhouse is 

not a new feature on campus, the UI Gardeners also hope they 

can make it more well-known, especially to students looking 

for a quiet reprieve in a bit of nature.

EADY, TECH, GROW: 

Emerging Technology in Agriculture 

Life on the farm isn’t what it used to be. Where there used to be farm hands and back-breaking 

labor, today there is automation, artificial intelligence, and agbots. Cory Hughes explains how 

today’s technology has created a new kind of farm and a new kind of farmer. 


READY, TECH , GROW 

Technology has always been a major 

contributing factor in how our lives are 

led. It impacts how we communicate, how we 

travel, and even how we eat. Advancements 

in agricultural technology are changing how 

we grow our food and manage its production. 

The ultimate goal of technology in agriculture 

is to increase yields, slash harvest times, and 

ultimately reduce costs and environmental 

impact. Emerging technologies not only 

impact farming on a small scale, but have 

a drastic effect on the large-scale system of 

food distribution as well. As new technology 

becomes integrated with modern farming, 

it results in improved production and easier 

supply chain management. 

“ 

The ultimate goal of technology in 

agriculture is to increase yields, slash 

harvest times, and ultimately reduce 

costs and environmental impact.“ 

Automated Agriculture 

Automation is the true focus of technological advances in 

agriculture, and it is already employed on farms around the 

world. Automation has come a long way since the days of 

mechanical timers, as modern automation requires very little 

assistance from humans. Systems are being created that can 

monitor, feed, and harvest crops from seed through to sale. 

Automation combines the use of a wide array of sensors, 

computers, feeding mechanisms, and everybody’s favorite: 

robots. Complete automation is a nearly self-sustaining 

system that can handle all day-to-day activities on the farm. 



It all but removes the need for human staffing, 

which can be good or bad depending on how 

you look at it. One of the core resources of 

automation is a vast network of sensors. 

Crop, air, and soil sensors are expected to 

be the backbone of future automated farming. 

While sensors are currently able to determine 

basics like pH, the sensors of tomorrow will 

be able to do much more than that. Soil and 

crop sensors will not only be able to read 

nutrient levels and EC, they will be able to 

perform more detailed analysis using infrared, 

electromagnetic, and acoustic means. Having 

more data can save crop growers time and 

money by allowing them to break from strict 

feed schedules to take a more as-needed 

approach. Equipment sensors will also be 

used to relay information from smart 

technology to a central 

control unit in order to warn 

of potential machinery 

failures or malfunctions. 

Just about any metric that 

can be measured will 

have a sensor constantly 

communicating with a 

centrally controlled artificial 

intelligence system. 

“ 

Currently, drones are being 

used on farms not only for surveillance, 

but application as well.“ 



“ 

Today, drone-like autonomous robots 

are starting to be used to perform 

tasks like planting seeds, tending 

crops, and harvesting.“ 

Artificial Intelligence 

The use of artificial intelligence, or AI, will make 

automated systems more adaptable to shifting 

conditions. Not only that, AI agricultural systems 

will be able to analyze, diagnose, and prescribe 

proper treatment programs for crops at a level of 

efficiency unmatched by humans. Now, we’re not 

talking about The Terminator when we talk about AI. 

For the time being, AI is simply a complex computer 

system that has the ability to adapt to new stimuli. 

AI systems in agriculture work to better coordinate 

mechanical systems, create feed schedules, diagnose 

illness, and ultimately increase yields and 

productivity. How do they do this? One of the more 

exciting technologies that will be coordinated by AI 

in agriculture is that of drones. 

Drones are popping up everywhere and are now 

regulated by the Federal Aviation Administration in 

the United States. They are cool and fun and seem to 

have way more practical uses than anyone could have 

imagined. Farmers can fly a surveillance drone over 

acres of crops and take real-time photos and video. They 

can also be fitted to monitor crop temperatures in the colder 

months. Currently, drones are being used on farms not only 

for surveillance, but application as well. Crop-spraying drones 

are one of the latest iterations of unmanned aerial vehicles (UAVs) 

found on today’s modern farm. Crop-spraying drones can apply 

pesticides or fertilizers and are unimpeded by rough terrain. Aerial 

drones aren’t the only ones having all the fun. Autonomous robots are 

also having an impact on modern farming. 



The Rise of Agbots 

The farms of tomorrow may no longer need people to 

grow crops at all. Today, drone-like autonomous robots 

are being used to perform tasks like planting seeds, 

tending crops, and harvesting. A variety of drone farmhands 

are starting to hit the market. Micro-seed planters, 

drone tractors, and weed-eating robots are slowly 

creeping into the agricultural mainstream. The idea is 

to create a swarm of automated robots controlled by a 

central AI that removes the possibility of human error 

and adapts to conditions to maximize yields and drastically 

cut time and increase efficiency. Automated 

farming machines work much like driverless cars. 

They are coordinated by GPS technology that precisely 

controls their locations and functions. The use of GPS 

technology is part of a much larger trend in farming 

known as precision agriculture. Precision agriculture 

has a few different names, including satellite farming 

and site-specific crop management (SSCM). Precision 

agriculture takes the most precise readings in topographic 

data and then combines it with sensor data on 

the ground to give a precise picture of crop needs. It 

is broken into four phases: data collection, analysis of 

variables, development of strategies, and implementation 

of practices. In the end, precision agriculture looks 

to maximize efficiency through precise data analysis 

using cutting-edge technology. 

“ New technology allows us to better 

understand our land, the soil, and ultimately, 

our crops.“ 

Automation, however, 

does not solve the 

problem of space. Along 

with modern technology, 

new systems of 

agriculture, such as 

vertical farming, 

are gaining in 

popularity as ways 

to maximize yields 

in a fraction of the 

space that traditional 

farms take up. As 

technology progresses, 

its contribution to 

securing our food supply 

has been undeniable. 

New technology allows 

us to better understand 

our land, the soil, and 

ultimately, our crops. 

It is with this better 

understanding that we 

can refine our methods 

and techniques that 

will ultimately lead to 

more efficient systems 

of production.

Control 

Grow: 

Controlled Growing 

Your Environments 

and Their Benefits 

Greenhouses allow growers to 

harness the power of the sun, 

the No. 1 resource for growing 

plants. Sealed and non-sealed 

rooms require the growers to 

mimic a natural environment. All 

three have their advantages and 

challenges. Which one may work 

for you? Read on to find out. 


CONTROL YOUR GROW 

G 

reenhouses can create the 

perfect controlled growing 

environment. After all, they allow 

plants to utilize the sun for the 

energy required for photosynthesis, 

to metabolize nutrients into biomass. 

Nature provides this for free. By 

controlling the environment within 

the greenhouse, we are able to offer 

crops a simulated environment 

coexisting with the nature outside. 

Therefore, many crops are viable 

inside greenhouses that could not be 

otherwise grown in that particular 

climate zone. Enclosed indoor 

gardens offer the same benefits. 

Spare rooms are perfect for growers 

to seal up and grow in. Virtually 

any plant can be cultivated indoors 

in a simulated environment much 

different from the geographic location 

of the building in which the room is 

located. As most buildings are kept 

at a comfortable room temperature, 

one of the rooms or areas of the 

building can be easily converted 

into an indoor garden. By using 

today’s available technologies and 

equipment, virtually any crop can be 

grown in a controlled environment. 

“ Depending 

on the amount of 

technology in the greenhouse, there can 

be great variance in production quality.” 



“ Greenhouses 

take advantage 

of the daily photons available and 

the spectrum of the sun.” 

GREENHOUSES 

Depending on the amount of technology 

in the greenhouse, there can be great 

variance in production quality. This is 

usually due to the greenhouse effect and 

low insulation ratings that greatly test the 

building’s ability to maintain an artificial 

environment. For this reason, some consider 

greenhouses to be more like outdoor 

agriculture, but given the correct level of 

sophistication, greenhouses can outperform 

many indoor gardens. 

Although most greenhouses use the 

method of exchanging air from the outside 

world and moving it throughout the 

greenhouse, there are other technologies, 

such as positive pressure or enclosed 

greenhouses, in which air is not simply 

moved through the greenhouse, but rather 

captured and recaptured while being 

manipulated and controlled using various 

equipment and technologies. 

Most greenhouses use the former. As 

the air is pulled through the greenhouse, 

heat is removed in the process. As heat is 

removed, so is CO 2 and humidity. In drier 

climates, greenhouses can easily be cooled 

by pulling air across saturated sponge-like 

pads on one end and with exhaust fans on 

the other. Another cooling method utilizing 

the evaporative cooling effect is highpressure 

misting in which the tiny fog-like 

droplets evaporate as they are moved 

throughout the greenhouse. 



In addition to exhaust fans, oscillating 

fans are placed throughout the greenhouse 

to move air randomly. This random 

disbursement of air distributes fresh CO 2 

throughout the greenhouse and moves it 

across the stomata of the plants, providing 

them with fresh CO 2 to breathe. In winter 

months, less air exchange is required for 

heat removal, so less fresh CO 2 is being 

provided to the stomata. Some greenhouse 

cultivators will supplement CO 2 with a 

regulator, controller, and injection system. 

Greenhouses take advantage of the 

daily photons available and the spectrum 

of the sun. High-tech greenhouses also 

take advantage of manipulating the 

sun’s cycles. By installing a blackout 

system, greenhouses can easily 

control the photoperiod, essentially 

controlling the season. Depending 

on the area’s available sunlight in 

winter months, some greenhouses may 

require supplemental lighting. Lighting 

technology continues to evolve and 

companies invest vast amounts into 

research and development as they 

attempt to duplicate the sun’s spectrum 

and photosynthetically active radiation 

(PAR) for optimal photosynthesis. For this 

reason, greenhouses have much inherent 

potential in crop yield and quality. 

The greenhouse effect can heat up the 

inside considerably higher than outside 

temperatures. This can be advantageous 

in the winter and challenging in the 

summer. By utilizing today’s latest technology 

and equipment, greenhouse growers 

are able to maximize yields and profits by 

minimizing costs in the long term. 

Indoor gardens are sometimes known 

for higher quality crops than greenhouses 

mainly because of increased temperatures 

created by the greenhouse effect. By 

controlling these important environmental 

parameters and using indoor gardening 

techniques, greenhouse growers are also 

able to produce high-quality crops. 

NON-SEALED 

INDOOR ROOMS 

Much like a typical greenhouse, air is 

being exchanged between the outside 

world and the controlled environment in 

a non-sealed or open room. 

The room is influenced by outside 

conditions, so tools and equipment are 

used to enhance the environment. Air 

conditioning is often needed to remove 

the immense amount of heat put off by 

the lights and other equipment. Exhaust 

fans and other ventilation equipment, 

such as ducting and filters, are used to 

direct heat outside during summer and 

can be reconfigured to take advantage of 

the heat from the lights during winter. 

Indoor gardens attempt to mimic nature. 

This means simulating the sun inside 

an enclosed indoor space. Fortunately, 

today’s agricultural lighting technologies 

allow for us to create indoor growrooms 

with up to 1,500 micromoles (µmol) per 

second, per square meter at a distance 

of one foot over the canopy (full noon sun 

is around 2,000 µmol per square meter). 

Today’s lighting technology delivers the 

appropriate daily light integral (DLI), 

or amount of daily light required, for 

virtually any plant to survive and thrive 

in an indoor garden. Lighting technology 

continues to evolve exponentially and, 

therefore, serious indoor cultivators 

should upgrade their lighting systems 

periodically to take advantage of 

improvements in efficiency and current 

technology’s best attempt to duplicate 

the sun’s spectrum. 

“ Another 

consideration while 

ventilating a non-sealed indoor room 

is to filter the incoming air in order to 

prevent dust and pests.” 



In an open-air exchange room, 

can-style exhaust fans and other 

cooling and ventilation equipment can 

be triggered by thermostat controllers 

capable of determining day or night and 

programming unique settings for each. 

For example, it is likely that less air 

exchange will be required at night due 

to decreased transpiration, and thus, 

decreased need for fresh CO 2. Night 

temps will also be lower, so fans won’t 

be needed to remove heat as often. A 

night program on a thermostat controller 

might be set to turn on exhaust fans at 10 

degrees cooler than a daytime setting. 

Another consideration while ventilating 

a non-sealed indoor room is to filter the 

incoming air in order to prevent dust and 

pests. If odor is of concern, the internal 

and outgoing air can be scrubbed with a 

cylinder-shaped carbon filter. The filter 

would ideally be placed up high where hot 

air is moving by default, and the exhaust 

fan would be used inline with ducting, 

pulling air through the carbon filter and 

across the light reflectors, removing the 

heat and odors. If an internal air scrubber 

is needed for additional odor control, use 

an additional carbon filter running with a 

can-style fan placed on top, which creates 

a loop in the room that absorbs the volatile 

organic compounds (VOCs) or odor-causing 

molecules and prevents smells from 

seeping out of the garden. 

“ Lighting 

technology continues to 

evolve exponentially and, therefore, 

serious indoor cultivators should upgrade 

their lighting systems periodically.” 



Finally, consider the temperature of 

the incoming air. In extremely cold 

or hot months, it may be necessary to 

buffer the air somewhere first, be it a 

closet, bathroom, or laundry room, for 

example. Otherwise, the plants would 

not like the outdoor air being pulled 

directly across the garden during the 

more extreme months. Pay attention 

to the maximum and minimum 

temperature and humidity reached 

between visits to the garden and make 

adjustments accordingly. 

A non-sealed indoor room moves 

outside air through the garden. This 

provides plants with the fresh CO 2 they 

need to breathe. Controlling the temperature 

and humidity of the air inside the 

garden can be done using these methods 

and produces a top-notch garden. 

SEALED INDOOR ROOMS 

A sealed room requires more equipment, 

but offers a way to completely control 

the environment. There are no inputs 

from the outside world. Everything 

affecting the environment happens from 

within. Lights produce heat that has to 

be controlled and cooled, except for in 

winter when the heat produced by lights 

can be used to bring up the ambient 

room temperature if necessary. In most 

areas, air conditioning will be needed 

because of the extreme amount of heat 

produced by the grow lights and other 

equipment. The air conditioning is the 

room’s only method of obtaining fresh 

air, so it is important to monitor CO 2 

levels. The air is not being exchanged in 

the room, so the plants are not receiving 

much fresh CO 2. 

Because the room is sealed and fresh 

CO 2 is not being brought in, it must be 

supplemented using a CO 2 injection 

system or a CO 2 generator. Either system 

would require the use of a regulator and 

a room controller to measure the amount 

of CO 2 in the environment and turn the 

unit off when desired levels have been 

reached. This is extremely important for 

safety reasons due to the inherent risk of 

using CO 2 in a controlled environment. 

Since CO 2 is heavier than air, it can 

accumulate to unsafe levels, especially 

in low areas such as basements, and 

as we cannot smell it, this effect can be 

dangerous. Therefore, levels must be 

monitored closely. 

Because the room is sealed and there 

is no ventilation, the humidity will 

increase rapidly, especially when plants 

are transpiring and growing quickly. 

Therefore, a dehumidifier will need to 

be used to remove excess moisture. In 

a sealed room, there is no ventilation to 

remove it otherwise. For added insurance, 

gardeners can add an extra layer 

of control and provide ventilation set on 

“ A 

sealed room requires more 

equipment, but offers a way to 

completely control the environment.” 

a hygrometer controller that would trigger the 

emergency ventilation fan if humidity levels 

rise too far above 60 per cent, which is where 

mold and mildew can begin to occur. In rare 

instances, such as in extra dry climates or 

when starting in an empty indoor growroom 

that is not already full of heavily transpiring 

plants, a humidifier may be necessary to bring 

the humidity up to at least 35 per cent. 

One way to keep the room sealed and still 

remove heat produced by the lights is to 

choose lighting fixtures with ducting attachments 

and sealed glass. They can use inline 

ducting with a can-style fan, pulling air 

through the light reflectors. The air can be 

brought in from outside of the room and 

passed directly over the lights and removed 

directly from the room, without mixing with or 

obtaining any of the air within the room. The 

room would remain sealed, and the ‘in’ and 

‘out’ holes would be cut just large enough to 

let the ducting pass through. 



Yet another way to remove heat from the 

growroom is to remove the items causing heat. 

It is obviously not feasible to remove the lights, 

but what about the ballasts? After all, they are 

designed to be a heat sink, so why not install 

them outside of the growroom? This can be done 

by installing a small hole to run ballast cords 

through. Some other equipment that produces 

heat, such as stand-alone air conditioners, are 

designed with ducting to help direct and remove 

the excess heat caused by the unit. 

Although completely sealed rooms provide for 

more parameters to control, understanding these 

methods and tools empowers growers to create 

a highly sophisticated, controlled environment 

capable of maximizing yields and producing 

top-quality harvests. 

“ Although 

completely sealed rooms 

provide for more parameters to control, 

understanding these methods and tools 

empowers growers to create a highly 

sophisticated, controlled environment 

capable of maximizing yields and 

producing top-quality harvests.” 

HAVE FUN & GET GROWING! 

While designing a controlled environment 

in which to grow, gardeners should consider 

the above options thoroughly before choosing 

whether or not to grow in a sealed or non-sealed 

room or even a greenhouse. One configuration is 

not necessarily better than another and it should 

be a subjective decision based on personal preferences 

and capabilities. If limitations arise, 

consider another option. Don’t be afraid to start 

small. Take enjoyment in letting your controlled 

environment grow alongside your garden and 

have fun with it. Happy gardening!

COULD 

DRONEs 

BE RUNNING 

YOUR GREENHOUSE SOON? 

Drones are everywhere these days. For the agricultural community, 

major headway in research and development could mean greater use 

of these little mechanized workers in gardens in the near future. 

BY TIM JENNINGS 

As president of a company that manufactures 

custom cases for drones and UAVs, I get an 

early look at advances in the drone industry. 

One movement that seems to be growing in 

strength is the use of drones in agriculture. 

As we’ve all grown accustomed to the idea 

of drones used in farming operations, I know 

this might seem like old news. After all, for 

several years, these mighty machines have 

been successfully scouting livestock and 

crops, capturing data to help farmers make 

precise season-based decisions, providing 

inventory information, identifying sick crops, 

and taking care of pesticide application. But 

recently, researchers in drone technology have 

been busy as bees developing what might 

become the most important technological 

advancements in agriculture and horticulture 

so far. These tiny workers, classified as micro 

drones, as well as regular-sized indoor drones, 

have been under R&D in institutions around 

the world for some time, but scientists in 

the US and Spain have made 

headway recently that 

could be bringing dronebased 

greenhouse 

applications into the 

mainstream soon. 


Micro Drone Pollinators — 

Bring on the RoboBees 

Micro drones are just what the name 

implies—ultra-tiny unmanned aircraft 

that do a variety of jobs. A major focus 

of the RoboBee project, a collaboration 

between researchers at Harvard and 

Northeastern University, is to develop 

tiny drone “swarms” capable of artificial 

pollination, among other things. It’s 

taken the research team about 12 years 

to design these little machines, which 

are capable of tethered flight thanks 

to tiny artificial “muscles” that allow 

each drone’s wings to beat 120 times 

per second. And when I say tiny, I mean 

really tiny— the drone’s wingspan 

measures only 1.2 inches. But don’t be 

fooled by its size. The RoboBee, weighing 

in at less than a real bee, is the 

culmination of some seriously heavy 

scientific collaboration between neurobiologists, 

electrical and mechanical 

engineers, computer scientists, and 

more. The latest collaborative advancement 

of this super team could be the 

thing that brings these machines to the 

mainstream in the coming years. 

Perching & Takeoff — 

Sort of a Big Deal 

In a recent article in the journal Science 

titled “Perching and Takeoff of a Robotic 

Insect on Overhangs Using Switchable 

Electrostatic Adhesion,” a Harvard 

research team reported that they’ve 

made real progress overcoming one 

of the greatest challenges in RoboBee 

advancement: making them stick to stuff. 

This ‘stick-ability’ is important because 

without it, RoboBees are forced to stay 

aloft at all times. Constant flight creates 

mechanical fatigue and quickly drains 

available on-board power—a particularly 

critical factor in the operation of 

such small, battery-powered machines. 

However, the researchers have figured 

out that electrostatic forces can keep 

the mechanical insects stuck to various 

surfaces, including the undersides of 

leaves. They also reported that generating 

this electrostatic force required less 

power than that needed to stay in flight. 

“ 

Mapping the Indoor Environment 

THE MULTI-DRONE SYSTEM also includes 

sensors that allow the drones to measure the 

temperature, humidity, luminosity, and carbon 

dioxide concentrations in soil and at various 

heights in the greenhouse environment.” 

For a super-tiny machine, pollination 

is one thing, but monitoring indoor 

variables is another. At this point, 

that type of data collection requires 

a larger drone. While the operation 

of larger drones doesn’t pose much of 

issue in wide-open, outdoor contexts, 

the inside of a greenhouse is a 

limited space that presents significantly 

greater challenges. 

A team of researchers at the Centre 

for Automation and Robotics in 

Spain are working hard and making 

some serious progress in overcoming 

those challenges. Just this 

year, the team published the paper 

“Heterogeneous Multi-Robot System for 

Mapping Environmental Variables of 

Greenhouses” in the journal Sensors. 

In the paper, the scientists describe 

a heterogeneous robot team they’ve 

developed to monitor environmental 

variables of greenhouses. The system 

includes both aerial and ground drones. 

Using an advanced multi-sensor application, 

the researchers have figured 

out how to enable these drones to 

communicate with one another and to 

“understand” their surroundings. And 

by understand their surroundings, I 

mean they can avoid smashing into one 

another, the greenhouse walls, and the 

plants therein. The multi-drone system 

also includes sensors that allow the 

drones to measure the temperature, 

humidity, luminosity, and carbon dioxide 

concentrations in soil and at various 

heights in the greenhouse environment. 

Plus, as with most horticultural drones 

out there, some are fitted with cameras 

that allow for easy visual monitoring. 

Drone-powered greenhouse automation 

probably won’t be taking flight this 

year or next, but we can rest assured 

that, considering the sort of advancements 

we’ve seen just this year, this 

technology is definitely headed our 

way soon. Happy gardening! M

Mushroom 

Power! 

WHEN TO USE 

MYCORRHIZAE ON 

YOUR PLANTS 

by Sally Nex 

Until recently, the study of mycorrhizal relationships 

between fungi and plants was a niche research area. 

But as word got out, gardeners understandably wanted 

to harness some of that mushroom power for their own 

plants. Modern production methods have sent mycorrhizae 

mainstream. You can now buy the spores of mycorrhizal 

fungi in all good garden centers and simply sprinkle them 

on your plants like any other plant growth stimulant. Here’s 

when it’s worth doing so, and when it’s not. 


MYCORRHIZAE 

Take a teaspoon and scoop some soil from 

the ground. You are holding a teeming 

metropolis right there: around a billion individual 

organisms, most of which you can’t 

see with the naked eye and all busily at 

work in complex, symbiotic relationships 

about which we know almost nothing. 

Garden soil could be described as the final 

frontier. We know as little about what goes 

on under our feet as we do about the outer 

reaches of the galaxy or the deep ocean floor. 

Soil scientists are like modern day explorers 

on a voyage of discovery, never knowing 

what they’ll find next, and every new revelation 

causes us to rethink our view of how 

plants interact with the world around them. 

One seismic reassessment of how we view 

the subterranean world of plants has come 

with the discovery of a huge group of microorganisms 

known as mycorrhizal fungi, 

microscopic mushrooms able to literally plug 

in plants to the soil like an electric cable. 

As we understand more about this hugely 

important group of soil microorganisms and 

the electrifying effect they have on plant 

growth, we’re also learning how to harness 

their power to improve results in the garden. 


MYCORRHIZAE 

Mycorrhiza Defined 

The word mycorrhiza is Greek for fungus and root, 

and that’s just what these mushrooms do. The fungi 

live in and around plant roots, siphoning off carbohydrates 

like glucose and sucrose from the plants. In 

return they send tiny, hair-thin hyphae (root-like filaments) 

into the soil around like a web to catch water, 

minerals, and other nutrients on behalf of the plant, 

effectively multiplying its root capacity several times 

over and leading to turbo-charged growth. 

There are thousands of different kinds of mycorrhizal 

fungi, but they divide roughly into two different 

forms. Ectomycorrhizae live in the soil around 

the plant and are usually associated with trees and 

woody plants. The mushrooms you see growing 

around trees, including many you can eat like chanterelles, 

are the fruiting bodies of ectomycorrhizal 

fungi, above-ground evidence of a complex subsoil 

relationship enabling the tree to connect more 

closely with the earth it’s growing in. Then there are 

the most commonly found group, the endomycorrhizae, 

or occasionally vesicular-arbuscular (VA) mycorrhizae, 

which live right among the cells inside plant 

roots. They form close relationships with around 80 

per cent of leafy plants, including vegetables like 

tomatoes, broad beans, and strawberries. Though 

they will die out where plants aren’t growing (for 

example, in a compost heap or a bare patch of soil), 

but when spores encounter roots they burst into 

life, colonizing them and then sending out hyphae 

hunting for food. 

Among the nutrients mycorrhizal fungi can draw 

from the soil for their hosts are phosphorus, nitrogen, 

manganese, copper, and zinc. The fungi act 

like a drawbridge against pathogens, making it 

impossible for them to get into the roots. When a 

plant is stressed, whether it’s because it’s too hot 

and can’t draw up water fast enough, is growing 

in the wrong type of soil, or was recently transplanted, 

mycorrhizae can help it recover and 

thrive. Just like humans eat yoghurt to reinvigorate 

naturally occurring gut bacteria and treat an 

upset stomach, mycorrhizae are like soil probiotics 

that help plants fight off diseases. 

“ We know as little 

about what goes on under our 

feet as we do about the outer 

reaches of the galaxy.”

MYCORRHIZAE 

“ mycorrhizae are 

like soil probiotics that help 

plants fight off diseases.” 

Supplementing Mycorrhiza 

You can now buy the spores of mycorrhizal fungi in all 

good garden centres and simply sprinkle them on your 

plants like any other plant growth stimulant. But it’s 

easy to waste your money. It’s not always necessary to 

add more to what’s already in the soil. For one thing, in 

normal, fertile garden soil, countless mycorrhizal fungi 

already live in harmony with the plants which grow 

there without you having to open your wallet at all. 

Soil is more delicate than it looks, though, so it’s quite 

possible to ruin your free supply of mycorrhizal fungi 

with clumsy gardening. Mycorrhizae only thrive in a 

healthy, undisturbed soil ecosystem in which they can 

form their filigree webs without some gardener coming 

along and trashing them with a spade. Many traditional 

gardening practices often do untold harm by breaking 

these fragile relationships between soil organisms. For 

example, autumn digging lays waste to soil ecosystems 

so thoroughly that they can take the next year to recover 

(by which time you’re on your way over with the spade 

again). And phosphorus-rich fertilizers can actively 

suppress mycorrhizal activity. 

So, look after your naturally occurring mycorrhizae 

and garden light upon the earth. Avoid digging wherever 

possible. Instead of the traditional end-of-season 

soil turning, just clear spent crops and then mulch 

thickly with organic matter instead. The worms pull 

it into the ground for you, leaving mycorrhizal relationships 

intact. This no-dig system naturally aerates 

and feeds your soil, so there’s no need to add artificial 

nutrients as well. Slow-release organic fertilizers, like 

pelleted poultry manure or bone meal, add naturally 

occurring minerals gradually to the soil, so you can 

continue to use those, but with mycorrhizae intact, your 

plants access those minerals more efficiently, so cut 

down the amount by about 20 per cent. 


MYCORRHIZAE 

A Fungal Boost 

Although healthy garden soils don’t need extra mycorrhizae, 

impoverished soils are a different matter. Earth that’s 

been tilled too often, former building sites full of rubble, 

or gardens made on soil exhausted through years of intensive 

agriculture will have ravaged ecosystems. You can tell 

simply by looking at the soil; dig up a spadeful and you’ll 

find earthworms are noticeably absent. 

Mycorrhizal fungi evolved hundreds of millions of years ago 

to facilitate prehistoric plant growth in soils as bad or worse 

than anything you’ll find today. They empower plant partners 

to colonize soils contaminated with heavy metals, pollutants, 

salt, and worse. They are the reason why hot springs panic 

grass can grow around geothermal springs topping 120°F in 

Yellowstone National Park, temperatures which would kill 

both plant and fungus if growing on their own. 

So, adding mycorrhizae to poor soils often helps kickstart 

the process of soil improvement. Scatter a teaspoonful 

into a planting hole and plant directly on top so the 

mycorrhizae are in direct contact with roots. The spores 

colonize them within weeks, providing an instant injection 

of life into starved soil. 

Mycorrhizal fungi are most commonly used when planting 

fruit trees and bushes, especially in thin soils when mycorrhizae-inoculant 

sprinkled directly over the roots before 

planting can dramatically speed up the rate at which they 

establish. You can also use mycorrhizae scattered along 

the bottom of drills or into transplanting holes to help most 

vegetables, too. The only exceptions are fast-growing crops 

like salads, which are ready to harvest before the mycorrhizae 

have time to get to work, and brassicas, one of the few 

plant groups that don’t use mycorrhizae at all. 

“ Although healthy 

garden soils don’t need extra 

mycorrhizae, impoverished 

soils are a different matter.” 

Potted Mushrooms 

In the artificial environment of a container, 

mycorrhizal fungi inject a little earthy 

goodness into multipurpose compost. 

Biologically speaking, compost is 

largely a dead environment—synthetic 

nutrients supply food for your plants 

over about six weeks, after which you 

just start adding more yourself. 

Recreate that garden soil magic by adding 

a little life to your container compost. 

Mixing in worm compost or home-made 

garden compost is often enough; rich and 

teeming with all sorts of bio-organisms 

as well as worms, it effectively revives 

sterile growing medium so your plants 

are growing in something approaching 

living soil. If you don’t have access to either 

compost or a wormery, though, mycorrhizal 

fungi will help. Containers are tough environments 

for plants, and mycorrhizal fungi 

help plants withstand the drier conditions 

and make better use of restricted nutrients. 

They’ll also help plants recover more 

quickly after repotting or root pruning. The 

exceptions are blueberries, which have 

their own ericoid mycorrhizae and can’t 

use the more common ones used in most 

commercially available products. 



87

MYCORRHIZAE 

“ Containers are 

tough environments for plants, 

and mycorrhizal fungi help 

plants withstand the drier 

conditions and make better 

use of restricted nutrients.” 

You only need to add mycorrhizal fungi once. 

Those web-like hyphae spread to fill the roomiest 

container, so when you replant, remove the top 

layer of compost only, leaving the colony intact. 

As long as you replant right away, the fungi 

happily buddy up with the next plant too. 

Use with Care 

Mycorrhizal fungi are living organisms, so when 

you buy them it’s a little like buying another 

plant. Store them with care—not in the fridge, 

where condensation makes conditions too damp, 

but in a cool, dry place like the shed or garage. 

They will lie dormant for up to two years; after 

that, the spores begin to die out so just use a little 

more product to guarantee enough viable spores 

(10 per cent extra per year is about right). 

Once you’ve applied your mycorrhizae, look 

after them. Your efforts and expenditure in adding 

mycorrhizae will come to nothing if you till the 

soil regularly, or fill it with phosphates from 

chemical fertilizers. Fungicides will also kill them 

off, of course, and tap water is also best avoided 

as chlorine is an effective fungicide. If you must 

use tap water, leave it in an open container overnight 

for the chlorine to evaporate. 

Mycorrhizal fungi have the power to make 

the difference between a so-so season where 

plants struggle to establish in sub-standard 

soils, and a truly productive veg garden full 

of vigorous, healthy plants with harvests to 

match. Target them well and use them with 

care, and those microscopic mushrooms can 

work their magic on your garden, too.

Operation 

Aphid: 

COMBATTING THE GARDEN PEST 

The bane of many growers, the diminutive 

aphid can cause big problems in your 

garden. While most plants can withstand 

minor aphid populations, the situation can 

get quickly out of control. Bryan Traficante 

provides insight on how to identify them 

and how to control these tiny sap suckers. 

BY BRYAN TRAFICANTE 


The aphid. The name hardly conjures 

up images of destruction, but that’s 

exactly what these little pests do best. 

A longtime scourge of gardeners and 

farmers alike, these sap-sucking insects 

thrive in temperate regions and multiply 

quickly if not controlled. 

Luckily, reducing and eliminating 

aphid populations is manageable and 

can be done quickly and inexpensively 

with products found around the house. 

Spotting Aphids 

Aphids are tiny and may escape detection 

by the naked eye. Color will vary 

depending on the species, but they all 

share a pear-shaped body with two 

antennae-like tubes protruding from the 

rear. In search of plant juices, aphids 

will attack all parts of a plant, causing 

the plant to lose nutritive sap. In some 

cases, aphids may transmit harmful 

viruses to the plant. In general, aphids 

prefer new growth and the underside of 

leaves. Look out for the following telltale 

signs of aphid activity: 

• Leaf curl: Aphids will attack the 

underside of a leaf, causing it to 

yellow, wilt, and curl inwards. Check 

the underside of a curled leaf and 

you may find an aphid hiding spot. 

• Sticky leaves and stem: 

Honeydew is a sticky, fluid-like 

byproduct of aphid feeding. It 

clogs leaf surfaces and can also 

attract ants. 

• Black leaves: The growth of 

black mold on honeydew is 

known as sooty mold. The 

mold greatly decreases a 

plant’s appearance and 

inhibits its ability to 

absorb sunlight. 

• Increase in ant population: 

As mentioned 

above, honeydew 

attracts ants, which 

in turn will protect 

aphids from their 

natural predators. 

• Distorted flowers and fruit: Flower 

buds and fruit that have been attacked 

by aphids may have a distorted and 

stunted appearance. 

Many plant species can withstand a 

minor aphid infestation; however, a more 

severe infestation can greatly impact 

your plant’s ability to grow and flourish. 

In cases where the root has been 

attacked, the plant may shrivel and die. 

Getting Rid of Aphids 

Quickly and Easily 

Like most maladies, early detection 

and treatment can be instrumental in 

warding off a more serious infestation. 

Here are a few quick and simple 

methods you can try using products 

from your own home. 

• Dish soap and water: A simple dish 

soap diluted in water works wonders as 

an insecticide. Dilute two tablespoons 

of dish soap in one gallon of water. Stir 

and transfer to a spray bottle. Before 

you begin treatment, spot test the 

soapy solution on a small area of the 

plant and wait a few hours. If the plant 

shows signs of damage, your solution 

may be too strong. When spraying 

an affected plant, be sure to spray 

both sides of the leaves, as well as 

any fallen aphids you may see. Upon 

contact, the soap solution will disrupt 

cell membranes and dissolve any exterior 

protective waxes that cover the 

aphid, resulting in dehydration and 

death. Make sure to rinse the plant with 

water after treatment. Sunlight will 

react with any residual soap solution 

and may cause a chemical burn (for 

this reason it’s recommended spraying 

in the early evening, as the plant 

won’t be exposed to as much sunlight). 

Repeat treatment every few days until 

aphid population is under control. 

• Lemon spray: This natural solution 

kills aphids on contact. Simply zest a 

couple of lemons into a pot filled with 

enough water to fill a spray bottle. Boil 

the mixture for 10 minutes then let sit 

overnight. Transfer the mixture to your 

spray bottle and begin the treatment. 

• Yellow bowl: A more passive and less 

invasive approach, this trick takes 

advantage of the aphid’s attraction to 

the color yellow. Simply fill a plastic 

yellow bowl with water and place it 

amongst the affected plants. The aphids 

will climb into the bowl and drown. 

Striking a Balance 

When treating your garden for pests, it’s 

important to keep in mind that you are 

altering the balance of an ecosystem. 

Many plant species are able to withstand 

minor aphid populations, and beneficial 

insects such as ladybugs and green 

lacewing larvae will help keep aphid 

numbers in check. However, when you 

believe aphid activity is beginning to 

have an adverse affect on your garden, 

it’s best to employ minimally invasive 

tactics that won’t harm the general biodiversity 

of your garden. 

“ 

When treating your 

garden for pests, it’s 

important to keep in mind 

that you are altering the 

balance of an ecosystem.” 

There are many products available 

at your local hydro store that combat 

aphids, but many growers prefer a 

DIY approach like the ones above 

if the infestation is caught early on. 

While they’re not the only ways to get 

rid of aphids, they’re a good, fast, and 

inexpensive start.

SUPPLEMENTAL CO 2 

: THE 

NEXT STEP TO 

Ridiculously 

Good Plants 

Your crops are on a killer nutrition regimen and 

living in an indoor growroom with on-point lighting, 

temperature, and humidity. What’s the next step 

towards getting ridiculously good-looking and 

well-performing plants? BRING ON THE CO 2 . 

BY ERIC HOPPER 



The greatest advantage of indoor 

horticulture is having ultimate 

control over light cycles, nutrition, and 

atmospheric conditions. A grower should 

do everything in his or her power to 

make sure their growroom’s lighting, 

nutrition, temperature, and humidity 

are precise and consistent. After all, it 

is only when a plant has access to sufficient 

light and balanced nutrients, and 

is provided with the appropriate atmospheric 

conditions, that it will be able to 

achieve its full potential. 

Once an indoor horticulturist dials in 

these crucial factors, he or she can take 

the next step toward maximizing the 

garden’s productivity. This can be done 

by supplementing CO 2 into the garden’s 

atmosphere. Higher levels of CO 2 have 

been shown to significantly increase 

plants’ growth rates and, therefore, the 

garden’s yield. On average, ambient air 

has around 350-450 ppm of CO 2 (it can 

be greater in urban areas with more 

air pollution). A grower who wishes to 

gain all the benefits associated with 

enriched CO 2 levels will typically 

increase CO 2 levels to 1,000-1,500 ppm. 

This enrichment can be achieved by a 

few different methods combined with 

specialized CO 2 control devices. 

CO 2 AND PHOTOSYNTHESIS 

Plants are unique creatures because 

they can directly convert light energy 

into usable energy for growth. 

This phenomenon is known as 

photosynthesis, which can be using the 

chemical equation: 

6CO 2 + 6H 2O + light energy = C 6H1 2O 6 + 6O 2.

ENRICHED CO 2 LEVELS WILL 

TYPICALLY INCREASE CO 2 

LEVELS TO 1,000-1,500 PPM. 



In the first part of the equation, there 

is CO 2 (carbon dioxide) and H 2O 

(water). When plants have access 

to these compounds in addition to 

light energy, they can produce the 

second part of the equation: C 6H1 2O 6 

(glucose) and O 2 (oxygen). 

It may look and sound complicated, 

but don’t be alarmed; you do not need 

a degree in chemistry to be a successful 

grower. Still, it is important to note 

that photosynthesis is a chemical reaction. 

Like other chemical reactions, 

photosynthesis can be affected by 

factors like temperature and the proper 

chemical compounds. 

One of these crucial chemical 

compounds is CO 2. Plants absorb 

carbon dioxide through the open 

stomata on their leaves. Transpiration, 

which helps keep plants at an even 

temperature, occurs when the stomata 

are open. However, transpiration 

results in the loss of water (another 

significant chemical compound for 

photosynthesis); so, to conserve water, 

plants regulate the amount of time the 

stomata are open. 

When a grower enriches the environment 

with CO 2, the amount of CO 2 

available for absorption increases 

for the length of time the stomata are 

open. In other words, the plant can 

absorb more CO 2 while still limiting 

water loss through transpiration. 

Some experiments have also shown 

that when provided with an increased 

amount of CO 2, plants will not open 

the stomata as wide, thus reducing 

the amount of transpiration. All in all, 

increased CO 2 levels will increase 

the efficiency of a plant’s water use. 

Assuming the plant has access to 

the necessary nutrients and light 

energy, the additional CO 2 absorbed, 

combined with the increased efficiency 

of water use, will increase the 

plant’s rate of growth. 

METHODS USED FOR 

CO 2 ENRICHMENT 

There are a few different ways 

to increase the level of CO 2 in 

the garden. For large spaces, the 

preferred method is generally a 

burner. CO 2 burners are fueled by 

propane or natural gas. As the fuel is 

burned, CO 2 is created as a by-product 

of the combustion. There are many 

different burners available and the 

size required generally depends on 

how large of an area a gardener is 

trying to enrich. Unfortunately, these 

devices also create heat in addition 

to CO 2. This is usually viewed as a 

disadvantage of CO 2 burners because 

most growers work hard to remove 

unwanted heat that is created by 

the intense lighting systems. Still, in 

commercial gardens or in very large 

growing facilities, burners are the 

most effective way to produce the 

large amount of CO 2 necessary to 

enrich the environment. 

" 

in commercial gardens 

OR IN VERY LARGE GROWING 

FACILITIES, BURNERS ARE THE 

MOST EFFECTIVE WAY TO 

PRODUCE THE LARGE AMOUNT OF 

CO 2 NECESSARY TO ENRICH 

THE ENVIRONMENT. 



Another common way to increase CO 2 levels is 

to use pure CO 2 contained in a tank or cylinder. 

This method of enrichment utilizes containers of 

compressed CO 2 teamed with a CO 2 emitter. The 

emitter regulates the rate at which the CO 2 is 

released from the tank and is normally combined 

with a timer or controller to determine when 

the CO 2 should be released. A compressed tank 

system is a great choice for many hobby growers 

because it is not only effective at increasing CO 2 

levels, but also will not create additional heat in 

the garden’s environment. 

The final method of CO 2 enrichment commonly 

used by indoor horticulturists is mycelium-based 

CO 2 systems. These devices can be purchased 

in buckets, bags, bottles, boxes, or mats, all of 

which contain strains of fungus combined with 

a food source for that fungus. As the fungus 

creates its mycelium (its equivalent to the vegetative 

process), it releases CO 2 as a by-product. 

This type of CO 2 enrichment is great for small 

areas, such as closets or small bedrooms. They 

are also relatively inexpensive, which allows 

a grower to experiment with CO 2 enrichment 

without making a huge investment. 

CONTROLLING CO 2 CONSISTENCY 

A grower should team a CO 2 device with some 

sort of controller so the emission rate of CO 2 can 

be regulated (mycelium-based CO 2 products are 

the exception as they can’t be controlled). Using 

automation devices that control the level of CO 2 

within the room is imperative to both the efficiency 

and the effectiveness of the CO 2 system. 

Many atmospheric controllers come equipped 

with built-in CO 2 control systems. There are also 

stand-alone systems available. 

" 

Newer, software-based 

CONTROL SYSTEMS OFFER ADDITIONAL 

CONTROL FEATURES, SUCH AS 

REMOTE ACCESS TO THE DEVICES AND 

DATA LOGGING. 



A good CO 2 controller will essentially 

automate the CO 2 system, controlling 

both the concentration (usually 

expressed in ppm) and the appropriate 

times for operation. Plants thrive 

in consistent environmental conditions 

and the concentration of CO 2 is 

no exception. The amount of CO 2 in the 

environment is detected by a ‘sniffer’, 

which will periodically sample the 

atmosphere’s concentration of CO 2 

and send a signal to the controller. 

If the concentration falls below the 

system’s set-point, the controller will 

then trigger the CO 2 device to turn on. 

On the other hand, a good controller 

will stop the CO 2 unit when exhaust 

fans are in operation so the CO 2 is not 

being removed from the garden as soon 

as it is emitted. Newer, software-based 

control systems offer additional control 

features, such as remote access to the 

devices and data logging. Data logging 

of CO 2 levels can provide valuable 

information over the course of a few 

garden cycles and can help a gardener 

determine the optimal concentration of 

CO 2 for their particular crop. 

TEMPERATURE AND 

NUTRIENT REQUIREMENTS 

As previously mentioned, photosynthesis 

is a chemical reaction and, like other 

chemical reactions, it can be affected 

by temperature. A typical indoor garden 

will have an optimal temperature 

range of 70-80˚F. An indoor garden 

enriched with CO 2 will have a slightly 

higher optimal temperature range 

(usually around 75-85˚F). 

It is also common for growers to 

increase the nutrient concentration in 

growrooms with increased CO 2 levels. 

This makes perfect sense because if 

the rate of growth increases, the nutrient 

requirements will increase as well. 

Since nutrient requirements vary, there 

is no perfect way to tell the exact nutrient 

concentration needed. That being 

said, a grower can expect to increase his 

or her garden’s nutrient concentration 

" 

an indoor GARDEN 

ENRICHED WITH CO 2 WILL HAVE 

A SLIGHTLY HIGHER OPTIMAL 

TEMPERATURE RANGE. 

by five to 15 per cent when enriching the 

atmosphere with CO 2. 

IN GENERAL 

Increasing the amount of CO 2 in the 

atmosphere of an indoor garden or 

greenhouse can increase growth rates 

when all other factors are considered. 

This will not only equate to faster vegetative 

growth, but also larger yields. 

For some growers, increasing the rate 

of vegetative growth will allow them to 

start fruiting or flowering more quickly. 

A shorter vegetative cycle can mean 

more garden cycles per year and a more 

profitable garden. 

Growers who want to invest in CO 2 

equipment should go all-in. In order 

to reach the full potential of a CO 2 

enriched environment, growers will 

not only need equipment for creating 

the CO 2, but also the adequate control 

devices to automate the system for efficiency. 

Without the full package, CO 2 

enrichment can be a disappointing 

venture with little gained in terms of 

overall financial investment. 

CO 2 enrichment should be viewed as 

icing on the cake. In other words, CO 2 

systems should be something that 

growers add to an already fully functional 

and productive garden. The basics 

of lighting, ventilation, and nutrition 

should always be the first priorities for 

any indoor grower striving for success.

New Year's 

by Kent Gruetzmacher 

Resolutions 

for Indoor Growers 

For indoor cultivators, it’s easy to fall into patterns 

of complacency when it comes to general growroom 

maintenance. If that’s the case with your operation, 

it’s time to kick those bad habits and adopt a 

proactive attitude regarding growroom upkeep. 

Many growers tend to forget that regular 

attention to the most remedial of chores 

can significantly affect the size and 

quality of indoor yields. Nevertheless, 

the coming of a new year should provide 

motivation for positive changes in one’s 

routines. Here are five areas of common 

garden and equipment neglect that 

should be remedied with the new year. 


pH Water 

Having the correct pH balance in your nutrient mixes, 

as well as your regular water supply, is essential for 

vital plant processes. Nonetheless, when repeatedly 

using the same nutrient recipe over extended amounts 

of time, cultivators might lose sight of their pH levels. 

This is because growers assume they should just be 

adding the same amount of pH up or pH down with 

recurrent nutrient mixes. Furthermore, some growers 

fail to check the pH of their water supply when 

watering with straight water. Both bad habits can have 

devastating consequences on the health of a garden. 

This is because the pH of both well and city water can 

fluctuate with changes in the weather. Even if you have 

been using the exact same nutrient recipe and water 

supply for years, resolve to take the extra time and 

check your pH levels with every watering. The digital 

hand-held meters out there make this step in the 

growroom super simple. 

Preventative Spraying 

It is easy to lose the motivation for consistent spraying 

if you’re not experiencing any observable issues with 

bugs, molds, or mildews. Nevertheless, if you fail to do 

preventative upkeep with regular spraying, greater 

problems can easily arise. Once bugs, molds, and 

mildews have taken hold of a garden, the work load 

involved with eradicating the problem is far greater 

than it is with pre-emptive measures. Consequently, 

precautionary spraying should be done at least twice a 

week to ensure a vigorous yield. Furthermore, different 

sprays should be rotated throughout the plant’s life 

cycle to ensure pests don’t build tolerances to specific 

products. Don’t neglect this simple chore in 2017. 

Fundamental Cleanliness 

Having a sterile environment in a growroom goes 

far beyond what is visible to the naked eye. Most 

plant nuisances are next to invisible in their infantile 

stages. Even if your previous crop was harvested 

completely free of visible pests and mildew 

problems, eggs and spores can still be lurking in 

the growroom. The conscious cultivator realizes that 

every component of a growroom needs to be sanitized 

on a regular basis. Pots, walls, floors, equipment, 

and reservoirs should be thoroughly cleaned with a 

mild bleach and water solution after each harvest. 

To ensure the most efficient performance of hoses, 

pumps, and sprayers, these tools should be bleached 

and sanitized regularly to eradicate the buildup 

of decomposing organic residues. The benefits of 

fundamental cleanliness cannot be overstated. 

This practice will help with future troubleshooting 

scenarios and save you loads of heartache. Put this 

New Year’s resolution at the top of your list. 

Cleaning Glass Hoods 

As all indoor gardeners are aware, electrical bills 

are one of the principal expenses in a growroom. 

However, for cultivators using air-cooled hoods, regular 

cleaning of the tempered glass on light fixtures is often 

overlooked. Over time, dust and dirt particles build 

up on both surfaces of the glass and considerably 

diminish the strength of the light that plants receive. 

Consequently, electrical bills remain inflated while 

usable spectrums of light slowly wane. For the new 

year, make your lighting as efficient as possible and 

plan on cleaning the glass of your light fixtures with a 

glass-cleaning product at least once per harvest. 

Dating Equipment 

If you keep your operation working all year long, 

it’s easy to lose track of the ages of bulbs, ballasts, 

carbon filters, and fans. Over time and with heavy 

use, the performance of these essential growroom 

components begin to decline. Therefore, it’s important 

to keep detailed records on equipment purchase dates 

and your accompanying receipts to ensure maximum 

performance. In conjunction with the use of a light 

meter, knowing the age of your light bulbs will help 

with decisions concerning the timing of replacements. 

Finally, keeping detailed accounts of purchase 

dates will help ensure all equipment warranties 

are honored when applicable. This detail-oriented 

approach to equipment maintenance will save you 

time and money in 2017.

HYDROPONIC 

GINGER & 

TURMERIC 

PRODUCTION 

BORED WITH GROWING TOMATOES, PEPPERS, 

AND LETTUCE? TRY GROWING SPICY RHIZOMES! 

by Dr. Lynette Morgan 

Growing hydroponic ginger and 

turmeric rhizomes provides dense, 

tropical, lush foliage over a period 

of many months and is also a great 

way of obtaining super fresh, 

healthy, flavorful spices. Adding 

new plants to your hydroponic setup 

is a great way to experiment 

with something different, grow a 

mature plant from pieces of readily 

available rhizome, and make the 

most of your tropical indoor oasis. 


HYDROPONIC GINGER & TUMERIC PRODUCTION 

Ginger and turmeric are members of 

the Zingiberaceae family of tropical 

and subtropical plants. They are wellsuited 

to protected cultivation in a 

warm, humid environment with plentiful 

nutrients and moisture-retentive 

substrate beds. 

Fresh rhizomes of ginger and turmeric 

have long been recognized for their 

culinary properties. They provide a 

slightly different, more aromatic flavor 

profile than their dried counterparts, 

owing to the presence of volatile 

compounds that are released when the 

rhizomes are cut or grated. 

Aside from their use in edible dishes, 

ginger and turmeric both have several 

medicinal uses, with fresh ginger used 

to alleviate nausea, while turmeric has 

long been used for its digestive, antioxidant, 

and anti-inflammatory effects. 

Turmeric contains many powerful 

compounds, including different curcuminoids 

and volatile oils like zingiberone, 

turmerone, and atlantone. Ginger 

contains gingerol, a natural bioactive 

compound known to have anti-inflammatory 

and antioxidant properties, as 

well as be useful as a digestive aid and 

as an antibacterial agent. 

Along with these medicinal and 

culinary properties, a well-developed 

ginger or turmeric plant provides a 

lush, tropical feel to any indoor garden, 

with their large, lime-green, attractive 

leaves. Turmeric plants also have the 

advantage of producing beautiful exotic 

blooms if conditions are conducive to 

rapid growth and development. 

Growing ginger and turmeric 

hydroponically ensures the rhizomes 

can be harvested at any stage. Fresh, 

young ginger rhizome has a crisp and 

juicy texture that lacks the fibers of 

older rhizomes. Its flavor is subtle and 

ideal for slicing thinly to eat raw or 

to make into pickled ginger for use 

in Japanese cuisine. Fresh turmeric 

has a mild, earthy flavor, and a fingerstaining, 

intense yellow color that is 

often used as a natural dye. Young 

harvested turmeric rhizome can be 

used immediately, grated into curries 

and other dishes, or blended with 

fruit and vegetable juices to create a 

supercharged smoothie. The harvested 

rhizomes may also be air dried and will 

keep for many months before being 

replanted for the next crop or consumed.

into a hydroponic system. 

PROPAGATION 

Ginger and turmeric are surprisingly 

easy to propagate from rhizomes 

purchased from the supermarket, 

specialist Asian grocery market, or 

online. Both are sold as fresh rhizomes, 

although they may have been in storage 

for several weeks to months before sale. 

In this dormant state, the buds present 

on the sides of the rhizomes remain 

relatively flat and difficult to see. Once 

conditions become sufficiently warm, 

these buds start to swell.

AND TURMERIC

ENSURES THE RHIZOMES 

CAN BE HARVESTED 

AT ANY STAGE.” 



Potted, spouted rhizomes can be grown 

as attractive houseplants. 

Small buds forming on ginger rhizomes 

kept in a warm kitchen after purchase 

are common, but turmeric often needs 

to be sprouted under warm and moist 

conditions before the young sprouts will 

form and become large enough to see. 

Turmeric contains plenty of buds on 

the sides and ends of the rhizomes, and 

even old and dried up rhizomes can

spring back to life once planted out into 

moist substrates. Fresh rhizomes can 

be broken into fingers or side shoots to 

increase the number of plants obtained 

from each—even small sections of 

rhizome usually contain at least one bud 

that will form a new shoot and young 

roots once planted. 

Optimal growing mixes during the 

propagation stage are sterilized perlite, 

vermiculite, coconut fiber, or rockwool, 

which helps retain moisture but at the 

same time, won’t become oversaturated. 

Pieces of rhizome are pushed into the 

growing substrate in a shallow tray to 

a depth of around two inches with any 

visible buds facing upwards. The tray 

is then best placed on a heated propagation 

mat or pad to speed up the rate 

of shoot formation. Ideal temperatures 

surrounding the rhizome pieces are 

around 82-90oF in the growing media 

at this stage. Buds should start to swell 

and grow along the sides of the rhizomes 

within two to four weeks, and as they 

emerge, young roots will form around 

the base of the shoot. 

THE FIRST SHOOT 

After the first leaf has emerged and 

unfurled, the sprouted rhizome can be 

transplanted to a larger container or 

growing bed and the first application of 

dilute nutrient solution applied. As the 

rhizomes are developing the first shoot, 

a moderate level of light that is typically 

used in a propagation area for clones 


and cuttings can be used, with a relative 

humidity of 80 to 90 per cent. Because the 

plants produce an underground crop of 

rhizomes, a soft, friable, moisture retentive 

growing substrate is ideal. Coco 

fiber fines mixed with 20 per cent perlite 

or a vermiculite/perlite mix is ideal, 

although the plants are quite adaptable 

to a range of other substrates. Large pots, 

buckets, and beds are ideal, provided the 

depth of substrate is at least 12 inches to 

allow for the large size of the root system 

at plant maturity. 

SYSTEMS & GROWING 

CONDITIONS 

Drip hydroponic systems are most suitable 

for growing ginger and turmeric, 

and these heat-loving plants will 

happily grow alongside tomatoes, capsicums, 

cucumbers, melons, and other 

fruiting plants because they have similar 

nutritional requirements. Once ginger 

and turmeric plants have two to three 

leaves, light levels can be increased to 

full strength, with similar intensities as 

many other high light crops grown in 

indoor gardens. While shading can be 

tolerated and doesn’t detract from the 

attractive nature of the foliage, it does 

reduce rhizome yields and increases the 

time to harvest. Ginger plants are best 

mounded up as the rhizomes develop. 

Mounding refers to adding more growing 

medium around the base of the plant, 

which helps increase yields and the 

quality of the harvested product. 

Day length is not an issue with these 

plants, but they do need warmth with 

optimal levels of 72-86°F, although both 

will happily grow at temperatures higher 

than this. Cool conditions will slow 

or prevent growth, so these plants are 

ideal candidates for growing outdoors 

in summer and bringing inside to 

overwinter and continue producing in 

winter in the tropical heat and light of a 

well-lit indoor garden.

HUMIDITY 

Ideally, ginger and turmeric prefer 

humid conditions of 70 to 90 per cent. 

By growing them in large, densely 

planted clumps, they can create 

their own micro climate of humidity. 

This, combined with a damp growing 

medium, tends to lead to optimal 

growth. Low humidity will cause the 

lower, older leaves to develop slight tip 

burn, which can be trimmed if necessary. 

Placing ginger or turmeric plants 

in the most humid area of an indoor 

garden is the best course of action. 

NUTRIENTS 

General-purpose nutrient solutions 

at an EC of 2.2-2.6 can be applied to 

ginger and turmeric crops. However, 

switching to a fruiting or bloom formulation 

at a higher EC seems to assist 

with intensifying the flavor and 

aromatic profile of the rhizomes. Your 

pH levels are best maintained around 

5.7 or 5.8 to maximize nutrient uptake. 

“ PLACING GINGER OR 

TURMERIC PLANTS 

IN THE MOST HUMID 

AREA OF AN INDOOR 

GARDEN IS THE BEST 

COURSE OF ACTION.” 


111

Turmeric is not only a spice, but can be 

also used as a natural, plant-based dye. 


REACHING MATURITY 

While both plants are long-term crops, 

turmeric will produce harvestable 

rhizomes more rapidly than ginger 

plants. Under ideal growing conditions, 

with sufficient heat, the first small 

turmeric rhizomes grown hydroponcially 

can be harvested in as little as six 

months, with main crop yields taking 

around eight to nine months. Ginger 

can also be harvested relatively young 

and small; however, full-sized, large 

rhizomes can take anywhere from 12 to 

18 months from planting. 

Ginger plants at maturity are generally 

larger than turmeric, although this 

depends somewhat on their variety 

and growing conditions. Ginger plants 

should be spaced 18 inches apart and 

turmeric plants, 12 to 14 inches apart, 

provided light levels are sufficiently 

high. This will give a dense canopy of 

foliage that makes a tall backdrop for 

smaller ornamental foliage and flowering 

plants in amenity plantings. While 

the flowers of culinary ginger are insignificant 

and not particularly attractive, 

turmeric blooms are delightfully exotic, 

won’t affect rhizome development, and 

are even edible, so these alone are worth 

growing the plants for. 

Harvesting ginger and turmeric is 

relatively simple. Turmeric plants will 

develop foliage yellowing and dieback 

once the rhizomes are fully mature. 

Plants can be harvested before this 

stage as young rhizomes are more tender 

and fully usable, but they won’t store 

for extended periods of time. Plants can 

be pulled from the growing substrate, 

which has been allowed to dry down for 

a few days, and the rhizomes plucked 

from the root system. 

Alternatively, a rhizome or two can 

be generally removed form the plant 

while it is still growing by digging 

down around the base of the stem and 

removing the largest that has formed, 

then replacing the substrate. The plant 

will continue to direct reserves into 

the remaining rhizomes, allowing a 

longer period of fresh rhizome harvest. 

Once harvested, the skin on ginger and 

turmeric rhizomes is so thin it can be 

gently washed before immediate use. 

For longer term storage, they require air 

drying to cure the outside layers of the 

rhizome or stored wrapped in plastic 

under refrigeration. 

“ THE FOLIAGE OF TURMERIC 

CAN BE PRONE TO SPRAY 

DAMAGE FROM THE REGULAR 

USE OF INSECTICIDE OILS, SO 

THESE ARE BEST AVOIDED.” 

PEST CONTROL 

Under optimal growing conditions, 

ginger and turmeric are relatively 

hassle-free crops and seem remarkably 

immune to common exotic plant problems 

such as root rot or die back due 

to overwatering. They can, however, 

suffer from common pest issues. With 

an indoor garden or greenhouse these 

typically include fungus gnats during 

the propagation phase, and mites, 

thrips, and whiteflies on more mature 

plants, which can all damage and 

discolor the foliage rapidly. 

Early identification and control of pests 

is recommended, and the large, dense 

canopy may also provide a suitable 

environment for the use of integrated 

pest management (IPM) with introduced 

predator and parasite insect controls. 

The foliage of turmeric can be prone to 

spray damage from the regular use of 

insecticide oils, so these are best avoided 

unless plants are close to harvest maturity 

when leaf marking is less of an issue. 

While ginger and turmeric may be familiar 

as dried spices readily available in 

pre-packaged form, the young rhizomes 

freshly harvested from a hydroponic 

garden provide a more powerful punch 

when it comes to flavor and bioactive 

compounds. They are also fun and attractive 

to grow, so why not shake things up 

this year and give it a try? 


114 Maximum Yield USA | January 2017 

BY SARA ELLIOTT | While herbs 

offer some impressive health 

benefits on your plate, they can 

present some big challenges in the 

garden. Incorporating these little 

plants into herb spiral, however, 

help make the journey from farm to 

table a little easier for everyone.

Herbs can be headstrong and unpredictable. The 

mojito mint you reserve for special occasions can 

make a bid for more space by overrunning your favorite 

perennials, and the precious and pricy saffron 

bulbs you planted last season might easily give up the 

good fight if your soil doesn’t drain quickly enough. 

After a bad experience, though, most gardeners try 

again—only in a different flowerbed or in patio pots 

where they can keep a wary eye on them. Another 

option to maintain the herbs together is to incorporate 

them into an herb spiral. This gives them a better 

opportunity to look their best and gardeners an opportunity 

to provide them with the special care they need. 

Consider this type of bed the 

herb lover’s version of vertical 

gardening, and a permaculturist’s 

dream of a generous, efficient, 

yet flexible growing space.” 

WHAT’S AN HERB SPIRAL? 

If you’ve seen a snail shell or chambered nautilus, you 

have a general idea of the shape an herb spiral will 

take. In this case, as the curve winds from the outside 

toward the center, the reinforcing walls become gradually 

taller, topping out at the center point of the spiral. 

Gaps between the walls are backfilled with soil and 

planted out with herbs. The structure of an herb spiral 

produces artificial microclimates, which result from 

the small, yet significant environmental variations that 

occur as the spiral changes direction and elevation. 

Consider this type of bed the herb lover’s version of 

vertical gardening, and a permaculturist’s dream of a 

generous, efficient, yet flexible growing space. It can 

house plenty of herbs because specimens are planted up 

as well as out. Also, its shape makes it possible to locate 

a spiral garden close to a kitchen door for convenience 

or in a postage stamp-sized urban garden.

HERB SPIRALS 

THE ADVANTAGES OF AN HERB SPIRAL 

Herb spirals offer the gardener an opportunity to cultivate 

different environmental zones, modifying the soil 

to suit specific plant specimens. Everything can work 

together in the microcosms of the spiral garden. This 

same circular, elevated structure will also help keep 

plants from sprawling, and balance the problem of 

placing dense small plants close to taller, spindly ones. 

There’s more good news. If you live in an area 

where water rationing or drought conditions are a 

problem, an herb spiral offers a structure naturally 

designed for optimal watering efficiency. When you 

water, moisture remains within the spiral, filtering 

down from the top to the bottom. Just place moisture 

loving plants at the bottom of the spiral, and leave 

Mediterranean and other drought-tolerant varieties 

toward the top. So, not only do you water less, but the 

different zones—dry on top and moist down below— 

offer plants exactly what they need. 

Last, but not least, herb spirals look good. They are a 

hardscape features, same as fishponds or stone planting 

boxes. With proper planning, you can install one in 

a weekend using any of a variety of materials you may 

have on hand, including rocks, stones, pavers, cinderblock, 

bricks, or even recycled bottles. An elaborate 

spiral can even incorporate a water feature, like its own 

mini pond. It all depends on your budget and the look 

you want to achieve. Once assembled, however, all 

spirals make a natural focal point that will help balance 

the corners and straight lines that tend to make a backyard 

landscape look more rigidly cultivated than pastoral. 

They’re also particularly eye-catching and dramatic 

when viewed from a second-story window or deck. 

If you live in an area where water 

rationing or drought conditions are 

a problem, an herb spiral offers 

a structure naturally designed for 

optimal watering efficiency.” 

HOW TO BUILD AN HERB SPIRAL 

Layout and Location 

Before you start thinking about turning your whole backyard 

into a huge herb spiral, there are some scale issues 

to consider. All those herbs you’ll have growing around in 

circles need to be maintained and harvested. To do that 

effectively, you’ll have to be able to reach into the center of 

the spiral. That limits the overall size to about twice as wide 

as your outstretched arm. You can make a spiral smaller or 

larger than that, but a smaller spiral won’t produce as many 

useful microclimate zones, and a larger one will be harder 

to keep up. The most practical size is about six to 6.5 feet in 

diameter. A gradual rise to the center should give a six-foot 

spiral a maximum elevation of about 39 inches. 

You’ll also need to choose a plant-friendly spot for your 

herb spiral. Make sure it gets at least six hours of sunlight a 

day, and it’s large enough for both the spiral and a walkway 

around it. Also, plan for the special needs of any extra 

features you have in mind, like access to running water and 

the availability of electricity. 

Materials 

As I said before, there are lots of potential choices here. 

From reinforced brick and concrete to loose stones, you can 

spend an entire season pondering the merits of different 

hardscape decisions. So, rather that focusing on aesthetics, 

let’s look at some practical considerations. 

Brick and stone are both popular, and you’ll require about 

two cubic yards of either material for a spiral. Rebarreinforced 

brick will potentially last for decades, but at a 

higher cost than other options, especially if you choose to 

have it professionally installed. Using a rustic material like 

stone produces a sturdy spiral, but it can be a challenge to 

dry stack as the height of the reinforcing wall increases. 


Large stones can hog a surprising amount of potential 

planting space. Both brick and stone hold in the heat, 

which could be important in cold or borderline climates 

where a jump of a few degrees can mean the difference 

between keeping your favorite herbs in handy reach 

and having to source them at the market during the fall. 

Hardscape materials like these can be heavy, too. If this 

is a DIY job, don’t discount the effort involved in toting 

heavy loads from your driveway to the far reaches of your 

property. If you’re going to use it, position the stone pile 

nearby and enlist the aid of some helpers if you can. 

Both brick and stone hold in the 

heat, which could be important in 

cold or borderline climates.” 

Although less popular, prefabricated synthetic and recycled 

materials are options, as are wood, bamboo, metal pipe, and 

creative solutions like wire mesh frames filled with small stones. 

After you decide on a structural foundation for the spiral, start 

assembling the stuff you’re familiar with: soil; amendments as 

needed; organic material like grass clippings, leaves, straw; 

and bark or another mulch product. For a six-foot spiral, you’ll 

need between 12 and 14 cubic feet of soil and organic matter. 

Installation 

There are lots of interesting ways to construct herb spirals, 

but let’s walk through some basic steps you can use as a 

jumping-off point. First, clear your planting area of weeds 

and debris, and cover the spot with a weed deterrent like 

garden fabric, newspaper, gravel, or cardboard. Next, install 

a stake at the center of the spot you’ve prepared and make 

a mark at the 39-inch point. Then, place another stake three 

feet or so from the center. This is where the beginning—that 

is, the lowest point—of the spiral will be.

HERB SPIRALS 

For example, you may want your spiral positioned to 

show off a decorative element like a pond or statue 

that you plan to incorporate. No matter the orientation, 

though, just be sure to pay attention to the different 

zones you’re creating, and remember that a southern 

exposure will be sunnier, hotter, and drier. 

Now that you have everything laid out, begin by putting 

down a layer of stone or other structural material in the 

shape of the spiral you’ve drawn on your chosen spot. 

Once it’s in place, measure to make sure you’ve left 

enough space for the plants and step back to check that 

your curves look clean and the overall shape is pleasing. 

Next, start building additional layers, moving along 

the spiral to increase the elevation gradually. If you are 

dry stacking stones, intersperse smaller rocks, gravel, 

and organic material to fill cracks and create even and 

steady layers. Remember, the finished spiral should 

be 39-inches tall at the center point. Use the mark you 

made on the center stake as a guide. 

Then, begin adding prepared soil to the trench, slowly 

filling it as the walls of the spiral grow. Slope the soil 

surface so it’s somewhat higher in back where it rests 

against the stone support wall. 

Once the installation is complete, water the soil and 

let the spiral settle for six weeks or more. This is also 

a good time to include some accessories that will help 

you manage and monitor your spiral in the coming 

months and years. To this end, installing a soaker hose 

assembly is a good option, as is adding a rain gauge or 

investing in a monitoring system with multiple sensors 

that will help you understand and control the different 

microclimates within your new vertical bed. 

If you have trouble working out the 

shape, you can employ a loosely 

wound garden hose as a guiding 

tool. Then, use chalk, stones, paint, 

or twine to mark the spiral once 

you’re satisfied with the layout.” 

Now, draw a preliminary spiral using the stakes as a 

guide. In a six-foot spiral, aim to create three coils: two 

large and one smaller at the apex. Also, each soil-filled 

“level” you’re creating should be 12- to 15-inches wide. 

You can get away with less, however, if the herbs you 

plan to plant are relatively small. Also, keep in mind 

that the reinforcing material you choose will have 

an impact on the available planting area the spiral 

contains. If you have trouble working out the shape, you 

can employ a loosely wound garden hose as a guiding 

tool. Then, use chalk, stones, paint, or twine to mark the 

spiral once you’re satisfied with the layout. 

The orientation of the spiral can also be important. 

It’s traditional to place the ground level opening—the 

beginning of the spiral—facing north. This benefits 

moisture-loving plants like the mints, sweet woodruff, 

lemon balm, and watercress, which thrive when grown 

in mild, north-facing locations. This simple, but effective 

strategy isn’t always the best choice, though. 


Just be sure to pay attention 

to the different zones you’re 

creating, and remember that 

a southern exposure will be 

sunnier, hotter, and drier.” 

PLANTS FOR YOUR HERB SPIRAL 

After letting the herb spiral settle, it’s time to add 

some culinary, medicinal, fragrant, and fun herbs. 

Stick with smaller plants and shrubs, avoiding 

trees like bay that will outgrow the space and could 

present big headaches come transplant time. Here 

are a few popular options that will take advantage of 

the different zones in your spiral’s design: 

Dry and sunny (top) - oregano, sage, rosemary, 

tarragon, saffron crocus, lemongrass, lavender 

Good light, drains well (mid, south-facing) - basil, 

dill, marjoram, cilantro, thyme, calendula (pot marigold) 

Moist with partial light (low to mid-level) - chives, 

parsley, chamomile 

Moist and shady (low, north-facing) - mints, lemon 

balm, catnip 

If you have a small spiral, or ended up with one that has 

some narrower planting areas, dwarf versions of popular 

herbs like sage, rosemary, and basil are available. 

While spiral growing is fantastic for herbs, it’s also 

a great way to raise your favorite flowers and other 

plants, including some of the smaller vegetables. Just 

make sure you can distinguish the herbs you plan on 

using for culinary and medicinal applications from 

strictly ornamental plants that may be toxic.

INTRODUCING: 

Slucket 

by Lacey Macri 

Have you heard about 

the Slucket, yet? More 

than just a fun thing to 

say, a Slucket is a simple 

hydroponic grow bucket 

invented and made right 

here in the USA. Slope + 

Bucket = Slucket. 

After coming across Slucket at the 

Maximum Yield Expo in Novi, 

Michigan, in spring 2016 for the first 

time, I knew it would not be the last. 

Their innovative growing technology, 

combined with their positive spirit, 

encouraged me to delve more into what 

exactly they are doing and how their 

presence in the industry will impact 

growers around the globe. Joshua 

Carmody, director of operations at 

Slucket, shares how they got started, 

what they’re focusing on these days, and 

where they see themselves in the future. 

How and when did Slucket 

get its start? 

Matt Carmody, CEO of ZW Plastics 

and owner of Slucket, created the 

Slucket system after being an avid 

gardener for many years. Between 

the two companies, we own both the 

plastic recycling centers and injection 

mold shop where the Slucket is manufactured 

in Michigan. This is a onestop 

shop from beginning to end. The 

Slucket 10-gallon bucket has been on 

the market since January 2016, when 

we did our first industry trade show in 

Denver, Colorado. Our biggest takeaway 

from the expo was that there is a huge 

demand for a multiple-use hydroponic 

system that uses containers such as 

ours. We have since improved upon our 

original design, which hatched a new, 

revolutionary way of using the Slucket. 

What is your signature product 

and how does it work? 

Matt created a new process for recirculating 

deep water culture (RDWC) with 

the Slucket. The Posiflow by Slucket 

system has two manifolds: the lower 

manifold to force the water up through 

the port at the bottom of the Slucket, 

and the top manifold for returning 

“ 

ONE OF THE GREATEST 

FEATURES OF THE POSIFLOW 

SYSTEM BY SLUCKET IS THAT 

IT ALLOWS FOR THE TOTAL 

EVACUATION OF THE NUTRIENT 

SOLUTION, LEAVING ZERO 

RESIDUALS BEHIND WHEN 

DOING WATER CHANGEOUTS.” 


the water back to the control bucket. 

This allows growers to have a central 

bucket for controllers and dosing nutrients. 

One of the greatest features of 

the Posiflow system by Slucket is that 

it allows for the total evacuation of the 

nutrient solution, leaving zero residuals 

behind when doing water changeouts. 

This is achieved by using the same 

pump that floods the system to empty 

it as well through the centralized drain 

in each site. Growers will save massive 

amounts of time while maintaining a 

cleaner system overall compared to 

other RDWC systems. 

What’s been the response 

so far from gardeners? 

Growers with prior RDWC experience 

are thrilled they are finally able to 

drain the entire content of the system in 

minutes, which keeps the system cleaner 

and running optimally for longer periods 

of time. This feature helps to maintain 

a more sterile environment in RDWC, 

which is crucial due to the increased 

threat of waterborne diseases. The 

Posiflow system also allows each growth 

module to fully cycle every four minutes, 

so you don’t have to wait for the water 

to pull through your entire system since 

each module is independently fed. 

What level of expertise is your 

system best suited for? 

The Posiflow system by Slucket is userfriendly 

and effective for growers from 

beginners to advanced. Regardless of 

skillset, most growers value that the 

system runs efficiently and is easy to 

maintain. These systems come ready 

to grow within 10 minutes of opening 

the box. All the parts are packaged 

and ready to assemble with no need to 

cut or glue any pieces. It’s literally like 

putting Lego pieces together. 

Do you have other products or 

developments in the pipeline? 

We are working on producing a 

container for the soil and coco market. 

These containers will have a front 

drain port, making it easier to hook up 

drain lines. We are also developing 

multiple hydro bucket sizes to make the 

system more customizable. 

“ 

ALL THE PARTS ARE PACK- 

AGED AND READY TO ASSEM- 

BLE WITH NO NEED TO CUT 

OR GLUE ANY PIECES. IT’S 

LITERALLY LIKE PUTTING LEGO 

PIECES TOGETHER.” 

What does Team Slucket enjoy 

doing during their time off? 

Matt, the owner, is huge into dirt 

car racing. We sponsor a local car, 

and during the season we spend our 

Saturdays out at the track. Working in 

the garden is also a big part of how 

we spend our time—it’s a great way to 

relieve stress! 

Where do you see the business 

in the future? 

We have many containers that will hit 

the indoor gardening industry within 

the next five years. In this market, we 

ultimately aim to offer the only growing 

container gardeners will ever need. 

Through our extensive experience with 

the entire industrial process of recycling 

plastics, we have overengineered the 

Slucket to ensure durability in the growroom. 

Our team also plans to take our 

patents into other markets, as there is 

a universal demand for containers that 

have a bottom drain.

BRING 

ON THE 

BERRIES: 

A BEGINNER’S GUIDE TO GROWING BERRIES IN CONTAINERS 

There is a high reward factor when you pick your 

own berries just to snack on or for your favorite 

dessert recipe. It’s even better when the berries 

grow right outside your door. Kate Van Druff 

gets us ready for berry season by explaining the 

intricacies of growing strawberries, raspberries, 

blueberries, and blackberries in containers. 

BY KATHRYN VAN DRUFF 



123

BRING ON THE BERRIES 

Strawberries, raspberries, blueberries, 

and blackberries taste wonderful 

right off the plant and offer myriad uses 

in the kitchen far beyond simple snacking. 

Imagine picking your own mouthwatering 

berries fresh from the plant 

whenever you feel the slightest pang of 

hunger or sending your kids to pick their 

own snack. A perfect addition to breakfast, 

salads, or desserts, berries can be 

one of the most enjoyable fruit-bearers 

to grow at home. Plenty of recipes and 

inspirations lead to delicious culinary 

creations and your yields will happily 

freeze for future use. Best of all, you can 

grow berries at home in containers with 

very little regard to the size of your yard. 

Easily avoid the oft-exorbitant cost 

of buying berries by the carton when 

you chose to grow your own varieties 

from the comforts of home, be it in your 

sunroom or on your balcony, porch, or 

patio. The biggest pieces of the puzzle 

in growing your own berries typically 

involve choosing the right pot size and 

ensuring adequate drainage. Whether 

you wish to grow raspberries, blueberries, 

strawberries, or another variety, 

you can find great success both indoors 

and out. Start planning for spring and 

consider these tips to help your homegrown 

berries thrive. 

GROWING STRAWBERRIES 

IN CONTAINERS 

Especially suited for growing in 

containers, strawberries take little time 

and effort to establish a successful 

setup. Start with an everbearing variety 

like Ozark Beauty, Tillicum, or Quinault 

for the most favorable results. 

Choose the Right Container: Delightful 

as a first choice of berry to grow in 

containers, strawberries even have their 

own style of container, a strawberry 

jar, which is shaped like an urn and 

boasts individual openings where you 

can plunk down a plant on all sides of 

the container. Strawberry jars make a 

fine choice so long as you don’t let your 

berries dry out for too long in the hot 

sun. Other ideal containers include standard 

flower pots; half-barrels; long, low 

planters; and hanging baskets. 

Planting the Berries: Before you fill 

your strawberry jar, consider creating a 

drain tube. Using a length of PVC pipe, 

a drill, some gravel, and a bit of mesh 

or pantyhose, you can make this handy 

watering tube to help evenly distribute 

the water. Drill holes evenly throughout 

the tube, add gravel, seal the ends 

with permeable fabric, and place it in 

the center of the pot. You can fill around 

the drain tube with a pre-fertilized soilless 

mixture or one that already contains 

a bit of compost. Once in place, put a 

strawberry plant in each opening of the 

jar and gently tamp to incorporate it 

with the potting mix. Add several strawberry 

plants to the top of the planter 

once you’ve filled the side openings. 

If you are worried about the soil and 

plants washing away out of the openings, 

you can add peat moss or a bit of 

newspaper to the base of the plants. 

Let the Sun Shine: Ideally, strawberries 

enjoy full sun to partial shade and 

temperatures of 70-85°F (21-29°C). For 

the first few days, though, you may 

wish to keep the pot in the shade until 

the plants acclimate. Depending on 

your climate, you may also need to 

adjust location and watering intervals 

to better suit the plants’ needs. 

“ 

A PERFECT ADDITION 

TO BREAKFAST, SALADS, OR 

DESSERTS, BERRIES CAN BE ONE 

OF THE MOST ENJOYABLE FRUIT- 

BEARERS TO GROW AT HOME.” 



125


Monitor the Moisture: Strawberries don’t 

like to go to bed with wet feet. Make sure 

you water your berries early enough in 

the day so that the water has a chance to 

soak down to the roots without leaving 

the soil a soggy mess. 

GROWING RASPBERRIES 

IN CONTAINERS 

Raspberries tend to produce their yields 

in the summer or the fall. Choose from 

numerous tasty varieties, including red 

raspberries, black raspberries, and even 

golden raspberries. Like strawberries, 

everbearing varieties (autumn-fruiting) 

may be the best place to start, offering a 

smaller, sturdier plant that is less likely 

to require a support structure. 

Choosing the Right Container: At 

a minimum, look for a pot with a 

24-inch diameter. You can also grow 

raspberries in raised garden beds 

or directly in the ground, and it is 

advisable to do so once they’ve 

reached about three years of age. 

Planting the Berries: Start with a layer 

of gravel or broken seashells at the 

base of your container. Next, fill your 

raspberry container with a soilless 

potting mix specific to raspberries or 

a soil-based compost. Plant several 

raspberry canes around the edges 

of the pot, gently tamping the soil 

around them. Throughout the growing 

season, use a high-potash fertilizer to 

encourage greater yields. 

“ 

RASPBERRY PLANTS 

TEND TO PREFER A SUNNY SPOT 

WHERE THEY CAN BRUSH UP 

AGAINST EACH OTHER. PLACE 

YOUR POT IN FULL SUN, AIMING 

FOR ABOUT SIX TO EIGHT HOURS 

OF SUNLIGHT A DAY.” 

Let the Sun Shine: Raspberry plants tend 

to prefer a sunny spot where they can 

brush up against each other. Place your 

pot in full sun, aiming for about six to 

eight hours of sunlight a day. If possible, 

place the berries on the east side of your 

home or in a place where they will avoid 

some of the harsh evening sun. 

Monitor the Moisture: Raspberries in 

the ground typically need one good 

watering a week during the dry season 

and more frequent watering during 

fruiting season. For berries grown in 

containers, more frequent watering 

is expected, but carefully aligned 

with good drainage. Overwatering 

raspberries can lead to root rot and other 

problems. A long-time berry grower 

at the local landscape supply store 

shared a helpful raspberry watering 

trick with me this summer. He collects 

all the sticks from the Popsicles his kids 



127


eat and sticks them partway into the soil below 

his berry plants. Simply pulling the stick out of the 

ground reveals whether it’s time to give the plants a 

drink. Thirsty plants are easily detected by Popsicle 

sticks that are even in coloring and bone dry. Wait to 

water the ones that have a stick showing off a subtle 

shade difference or a touch of dampness. 

GROWING BLUEBERRIES IN CONTAINERS 

Dwarf varieties of blueberries can be a great choice 

for container gardens, although other types can 

also live and produce quite happily in pots. Look for 

drought-resistant berries like Bluecrop or those that 

best suit your climate. Northern Highbush Top Hat 

tends to do well in zones 3 through 7 while Southern 

Highbush Sunshine Blue thrives in zones 5 through 

10. Cross-pollination between plants can boost 

overall plant fruiting and production, so plan to 

grow at least two if possible. 

Choosing the Right Container: When beginning 

with blueberries, choose a five- to 10-gallon 

container. This size provides plenty of room for blueberry 

bushes, which have root systems that tend to 

be shallow and wide-spreading. 

Planting the Berries: Blueberries prefer more acidic 

soil, so fill the container with acid-lovers potting 

mix or a 50-50 blend of potting soil and peat moss. 

Avoid mixes containing redwood sawdust as it is 

not recommended for blueberries. Test the soil pH 

throughout the growing season to ensure it falls into 

the optimal range of 5.0 to 5.5. If needed, you can 

amend the soil with fertilizers to gradually increase 

the acidity of the soil. 

“ 

LOOK FOR DROUGHT- 

RESISTANT BERRIES LIKE 

BLUECROP OR THOSE THAT 

BEST SUIT YOUR CLIMATE.” 



Let the Sun Shine: Like many berries, blueberries prefer 

full sun. Aim to give them sunshine for about three-quarters 

of the day, with periods of partial shade limited to late 

in the day if possible. 

Monitor the Moisture: Like raspberries, watering when 

the soil gets dry is usually the best bet. You can use 

the Popsicle stick trick or simply stick your finger into 

the soil to see if the top few inches are dry. Water them 

when needed, but avoid overwatering. Each climate and 

container calls for different watering patterns. 

GROWING BLACKBERRIES IN CONTAINERS 

Most blackberries grow wildly and vigorously, making 

them less suitable for the container garden lifestyle. 

However, some thornless varieties can survive just fine in 

a large container with the proper care. 

Choosing the Right Container: Start with a container that 

is five gallons or larger for your blackberries. Large clay 

or ceramic planters, wooden barrels, and other wide, 

shallow styles work nicely. 

Planting the Berries: Blackberry plants require at least 

six inches of space for their roots to grow and develop. 

These berries tend to be rather invasive, spreading 

their roots across rather than down into the ground. 



Add broken pottery, gravel, or shells 

to the bottom of the planter for drainage 

and fill with a topsoil blend or 

regular potting soil. Depending on 

the size of your blackberry plants, 

you may need to add a trellis for 

support. Consider applying fertilizer 

regularly in small doses or once per 

year in slow-release format to ensure 

optimal growing conditions. 

Let the Sun Shine: Plan to place your 

blackberry containers in full sunlight 

where they will enjoy between six to 

eight hours of direct sun per day. 

Monitor the Moisture: Water blackberries 

when the top inch of the soil in their 

container is dry. 

WINTERING OVER YOUR BERRIES 

If you’ve grown your plants outside 

during much of their growing season, 

you’ve likely found a routine of care that 

seems to work best for each type of berry. 

As the colder months set in, however, 

you’ll need to adjust your care a bit. 

You may wish to bring your berries away 

from the elements for the coldest part 

of the year. Bring plants indoors or find 

a sheltered location outside, like under 

your deck or against a wall or shed. You 

can also add a layer of mulch to the tops 

or wrap a blanket or burlap around the 

containers for increased protection. 

While they won’t need as much watering 

in the winter, don’t let your berry 

plants completely dry out, either. Water 

raspberries, blueberries, strawberries, 

and blackberries just enough to 

keep them alive. At the start of the 

next growing season, top off the soil 

with new nutrient-rich mix as per the 

plant’s preferred medium. Then, after 

the danger of frost has passed, you can 

return your berry containers to their 

favorite sunny spots outdoors. 

OTHER KEY CONSIDERATIONS OF 

CONTAINER BERRIES 

In addition to all the basics, here are a 

few other important points to remember 

when growing berries in containers. 

• Picking is probably the most fun part! 

Get the hang of when to pick for best 

flavor and ripeness. With blueberries, 

resist the urge to pick right when they 

turn blue; wait a few days and then 

pick every three to five days thereafter. 

• Refrigerate berries to prolong their 

freshness. Freeze in zippered storage 

bags or ice cube trays for future use. 

“ 

BRING PLANTS 

INDOORS OR FIND A SHELTERED 

LOCATION OUTSIDE, LIKE 

UNDER YOUR DECK OR AGAINST 

A WALL OR SHED.” 

• Protect berry plants from birds 

with wildlife netting once fruit 

begins to develop. 

• Bring pots indoors or under shelter 

during heavy rainfall if you are 

concerned about overwatering. 

• Prune plants as needed, even while 

they are in containers. Research each 

individual plant’s pruning requirements 

for best results and a better 

yield next season. 

• In addition to pruning, you may also 

need to divide your plants into new 

containers if they multiply beyond the 

available space in their containers. 

• Move pots around your yard to ensure 

optimal conditions if desired. 

Once you choose your variety of 

berry, your container, and your 

location, you’ll be in good shape to 

enjoy delicious berries and the joy of 

growing your own year after year.

Baby 

it's 

Cold 

outside 

BY KENT GRUETZMACHER | Even though you're 

growing inside, the weather outside still has an 

influence. Follow Kent Gruetzmacher’s advice to 

keep your crop’s environment consistent even if 

the temperature outside is icy cold. 

ontrary to popular belief, indoor gardeners face challenges with 

Cthe changing of the seasons. This is because no matter how wellbuilt 

and insulated a growroom is, the weather, temperature, and 

humidity outside greatly affect carefully controlled indoor climates. 

However, the industrious indoor cultivator knows how to offset these 

climactic fluctuations and harness the changes to achieve a bountiful 

harvest. Now that January has arrived, there are several steps growers 

can take to overcome the weather. 

CO 2 ENRICHMENT 

The effectiveness of CO 2 enrichment 

in a growroom is dependent upon 

several significant factors, including the 

infrastructure of the room, the use of air 

conditioning, lighting logistics, and the 

type of CO 2 emission device being used. 

It’s important to note, however, that all of 

these variables interact with fluctuations 

emanating from the outdoor climate. 

During the warm summer 

months, air conditioning units in 

sealed rooms and exhaust fans 

in traditional rooms have to work 

overtime to keep the temperature 

at an ideal state, regardless of CO 2 

enrichment. The winter months allow 

for much more versatility concerning 

the use of CO 2, as colder weather 

plays an essential role in keeping 

temperatures cool in growrooms. 

With the flexibility afforded by 

winter temperatures, indoor gardeners 

should choose their CO 2 enrichment 

systems in conjunction with their 

specific needs. With sealed growrooms 

that continue to use air conditioning 

in the winter months, cultivators 

have the option of using notoriously 

warm propane CO 2 burners without 

overheating their rooms or overworking 

their air conditioning units. Propane 

CO 2 burners are beneficial largely 


“ 

The winter months allow for much more versatility 

concerning the use of CO 2 , as colder weather plays an essential role 

in keeping temperatures cool in growrooms.” 

from a convenience standpoint; propane tanks can be filled 

at almost any gas station, whereas CO 2 tanks must be filled 

at specialty shops. On another note, in the more novice and 

traditional exhaust-based growroom set-up, CO 2 enrichment 

is often not even an option in the warm summer months. 

Within this framework, environmental controllers dictate 

whether the exhaust is pulling air out of the room or the 

exhaust is off and the CO 2 emission device is operational. As 

these environmental controllers are dictated by temperature 

and humidity levels, cooler temperatures allow for more CO 2 

emission with less use of the exhaust. In either scenario, 

winter temperatures allow for a more constant level of high 

CO 2 in any indoor growroom. 

HUMIDITY 

Depending upon the outdoor climate of the operations in 

question, winter weather generally means a higher humidity 

level in growrooms for a couple of reasons. First, many 

geographies have far more precipitation outside during 

the winter months. Second, as the outdoor climate causes 

temperatures in growrooms to drop to a certain level relative 

to the amount of humidity in the air, the dew point in the 

microatmosphere can become problematic. This phenomenon 

occurs as the water vapor in the air (humidity) is released by 

reaching a cold air temperature threshold. The solidification 

of water vapor into condensed liquid form is referred to as 

‘dew’ in the standard climatological lexicon. The formation of 

dew within a growroom can lead to a number of cultivation 

problems, including both powdery mildew and botrytis. 

Therefore, the use of a dehumidifier in growrooms can help 

counteract potential problems caused by both 

outdoor precipitation and indoor humidity/dew 

point during the winter months. To help offset 

the cost of purchasing a dehumidifier strictly 

for the winter months, units often double as air 

conditioners to be used during the summer. 

TEMPERATURE 

With the influx of cold temperatures during the winter, 

indoor gardeners are faced with the challenge of providing 

consistent environments for their crops. Ideal indoor garden 

temperatures should range between 72 - 76°F, and this 

temperature range should be maintained with the lights both 

on and off. This is because temperature fluctuations of more 

than 15°F between “day” and “night” can contribute to the 

dew issues mentioned earlier. Furthermore, if growrooms 

reach temperatures below 55°F, plant growth is retarded and 

even halted. To combat temperature fluctuations between day 

and night in a growroom, it’s recommended that cultivators 

utilize a heating device. Economically savvy growers will 

look for heating devices that are multifunctional and can be 

used, in some form, throughout the year. For example, some 

mini-split air conditioning units can double as heaters in the 

winter, allowing for the streamlining of the electrical load of a 

growroom during all seasons. 

SPIDER MITES 

During all times of the 

year, spider mites pose 

a constant threat to the 

health of any indoor 

garden. However, the 

higher temperatures in growrooms during 

the summertime provide an ideal climate 

for spider mite eggs to hatch and mature quickly. As indoor 

gardeners have more options for regulating temperatures in 

the winter months, they have a far better chance of controlling 

spider mite populations than in summer. A growroom 

maintained at 75°F in December provides a climate far less 

conducive to spider mite growth and reproduction than a room 

kept at 80°F in July, studies show. Therefore, slightly cooler 

growroom temperatures in winter will work in unison with 

organic sprays to effectively eradicate these harmful pests.

New Year = 

New Plants 

by Chris Bond 

Start Off STRONG 

with the Right 

Seeds 

Did you know that heirloom seeds are not by 

definition organic? Or that hybridized crops 

do not necessarily pass along their traits 

through their seed? If you’re considering 

starting a garden from seed this spring, 

you’ll need to source the right kinds 

to suit your application. Doing so 

successfully starts with a guide to 

seed-buying lingo. 


NEW YEAR = NEW PLANTS 

When faced with the multitude of 

choices that exist in the world of 

seeds, things can get quite overwhelming. 

Fear not! The world of seed buying 

can be easily navigated by understanding 

a few key terms. 

What Seed Terms Mean 

Hybrid – A hybrid plant is one that 

resulted from the cross of two or more 

different varieties of plants. This is 

done for numerous reasons, but the 

main goal is to produce a plant that 

has a host of, presumably, desirable 

traits. They could be traits as superficial 

as brighter colors of fruits or 

foliage, or more practical traits such as 

cold tolerances. Hybridization is not the 

same thing as genetically modifying a 

plant; it has been done for thousands of 

years to produce crops that yield more, 

survive in colder temperatures, or are 

more resistant to diseases. 

Hybridized crops do not necessarily 

pass along their traits through their 

seed. Think of them like mules. Mules 

are hybrid animals resulting from the 

cross between a horse and a donkey, but 

are unable to reproduce. Hybrid plants 

may or may not be able to reproduce, but 

if they do, they will not pass along traits 

that are exactly like their own; rather, 

they will pass along unpredictable 

traits that belonged to their parentage. 

Hybrids that result from the first generation 

of a cross are known as F1 hybrids. 

In the previous example, the mule is an 

F1 hybrid. The progeny of F1 hybrids 

are known as F2 hybrids. They are not 

carbon copies of their parents and are 

generally not desired in the plant world 

because just like a box of chocolates… 

well, you know the rest. Seeds of F1 

hybrids need to be obtained each year. 

The word ‘hybrid’ does not connote 

anything relating to organic, conventional, 

or GMO. 

Open-pollinated seed – Unlike hybrid 

seeds, open-pollinated seeds will 

produce plants with the same traits 

as its parents. These are plants that 

were pollinated by natural mechanisms 

such as wind, rain, bees and 

other insects, or even with help 

from man. Open-pollinated seeds 

conserve genetic diversity, as they 

are not the result of crosses coordinated 

by breeders. All crops were 

originally open-pollinated crops 

“A hybrid plant is one that 

resulted from the cross 

of two or more different 

varieties of plants.” 

before being cultivated by man. 

Open-pollinated seeds are not 

necessarily organic. 

Heirloom seed – By definition, heirloom 

seeds must be open-pollinated. 

Not all open-pollinated seeds are 

from heirloom plants, but all heirloom 

seeds are developed from openpollination. 

Furthermore, an heirloom 

plant is a plant that has been 

cultivated for at least 50 years and 

whose origin can be traced. However, 

there is no consensus on exactly how 

old a plant must be to be considered 

“heirloom” other than more than 50. 

Some seed producers and organizations 

declare 75 years as the standard 

for heirloom certification, others 

100 years. Some plants, such as 

flower bulbs from Holland, have been 

continually cultivated for well over 

500 years. Heirloom seeds are not by 

definition organic. 



“GMO, or genetically 

modified organism, seed is 

seed that has been altered 

using DNA.” 

Organic seed – Organic seed is seed that is 

procured from plants that are certified organic 

by third-party organizations. The seeds were 

produced from plants that received no artificial 

fertilizers or pesticides in a manner consistent with 

organic production. There are numerous statewide, 

national, and international organizations that 

confer certified organic status to producers. Organic 

seed may be from heirloom, hybrid, or other classifications, 

but must not have come from any plant 

produced by non-organic means. 

Non-GMO/GMO seed – GMO, or genetically modified 

organism, seed is seed that has been altered 

using DNA. This is done in a lab setting to give 

seeds specific traits that they would not otherwise 

obtain through hybridization or other natural means. 

Sometimes referred to as “Frankenseed” these seeds 

are patented by their developers and are often modified 

to be resistant to the affects of other products 

manufactured by the same company. 

GMOs are highly contentious and controversial 

around the world. In many municipalities and 

regions of both North America and Europe, GMO 

seed has either been outright banned or is required 

to be clearly labeled as such so that the consumer 

can decide about acquiring the seeds or consuming 

products made from crops that were raised from 

GMO seeds. The manufacture, breeding, and labeling 

of GMO seeds is still a debatable topic and will 

likely be unresolved for many years. A seed packet 

bearing any language on its label referring to being 

non-GMO is seed that has not been collected or 


aised from plants that were genetically modified. It does 

not confer organic status to the seed, only that its origins 

are not traced back to a laboratory. 

Certified seed – Certified seed can mean any number 

of things, depending on the criteria of the certifying 

agency. In general, it means that the seed has been found 

through testing of some sort to be free of major diseases 

or pests. These results are obtained through a third 

party that analyzes plants growing out of the seed being 

trialed. It does not implicitly guarantee that the seeds in 

your hand are 100 per cent free from insect or disease, 

only that plants from the same lot were found to be free 

from them. The two most common pathogens agencies 

look out for are bacterial ring rot and root rot nematodes. 

Other certification may refer the origin of the seed in 

regards to its certified heritage or the conditions in which 

the plant that the seed was gleaned from was cultivated. 

It could also refer to the status and treatment of 

the workers involved in the cultivation and collection of 

that seed. There are numerous legitimate seed-certifying 

agencies, so it is worth a quick online search to learn 

what exactly a particular certification by a particular 

organization means exactly.

Characteristics of Healthy Seed 

Regardless of the origin or certified 

status of seeds, you want them to 

be healthy. Even certified organic, 

heirloom seed is useless to you if it has 

not been stored properly or is too old. 

Here are a few things you should keep 

in mind to ensure that you are using 

high-quality seeds. 

Storage – Whether storing seed you 

collected yourself or purchased from a 

reputable source, seed should not be 

stored under warm or moist conditions. 

Seed is best stored in dark, cool, and 

dry conditions. Note that seed should 

not come packaged in clear or seethrough 

packaging. Keep this in mind 

if you plan to store seeds in areas that 

are prone to moisture, such as many 

basements. Seed should also not be 

stored in the open such, as on a countertop 

or windowsill. This is fine if you 

are about to sow them, but is not effective 

for long-term storage. 







varieties of

plants.” 

of plants.” 

Age – Age is a tricky metric with seeds, 

but in general, you should always use 

seed that was collected from the previous 

season. The older the seed is, the 

less viable it is and the more age needs 

to be used to account for the reduced 

performance. This does not mean that 

seed older than one year old should be 

automatically thrown out; it means you 

should not expect the same performance 

per seed as younger stock. 

Of course, there are always exceptions. 

If you live in a climate with a shorter 

growing season, you may be better 

served by using slightly older seed, as 

it tends to mature quicker than younger 

seed, though often at the expense of 

higher yields. In nature, seed can lay 

dormant for many years before germinating. 

This is not the normal cycle 

for the types of annual crops that most 

gardeners grow. Most food and flower 

crops that are widely cultivated are 

those that spring forth from the most 

recent season’s seed drop. 

Texture – Healthy and viable seeds 

should not break when squeezed or feel 

sponge-like. They should be firm, plump 

(for their respective species), and have a 

hard casing. Any seed that is squishy or 

otherwise pliable should be discarded; it 

is likely diseased or very old. 

Size – Size is also a consideration with 

seed. It is rare that you will obtain 

an exact seed count when buying a 

package of seeds; generally, only the 

weight is reported on the packaging. 

If given the choice between “X” 

number of seeds per ounce or gram 

and some number less than “X” per the 

exact same weight, always go with the 

lesser amount. It may seem counterintuitive 

or that you are getting less for 

your money, but larger seeds (of the 

same species), more often than not, 

yield more vigorous plants than plants 

grown from smaller seeds. 

Additional Considerations 

After you have weighed your options 

and settled on your chosen varieties, 

there are a couple of things you should 

consider doing. 

Take note – Each packet of commercially 

sold seed should have a lot number or 

some other identifying code. Write it 

down somewhere or make sure to save 

the seed packet. You may need this

Stay sanitized – As you begin to sow 

your carefully selected seeds, remember 

that sanitation is important. Clean all 

your tools and containers before seeding 

and keep them clean during your work 

with seeds. If your seeds should have 

various bacteria or other pathogens, you 

don’t want to unknowingly spread this to 

your other seeds. 

Save for later – Once your seeds have 

yielded you the awesome plants,

consider saving some of their seeds 

for future use. Make sure to select the 

seeds with the same characteristics 

as those that you originally bought, 

remembering that if they were hybrid 

seeds, they will not produce a plant 

with the exact same characteristics that 

may have attracted you to it in the first 

place. Save heirloom and open-pollinated 

seeds for the best results and

THE FUTURE OF MAXIMIZING YIELDS: 

Combining Research and Big Data to Optimize Fertilization 

With a rapidly growing population, humanity is facing 

the challenge of how to feed itself in a sustainable 

way. Precise fertilization is key to maximizing yields, 

but in order to accomplish that on such a large scale, 

agriculture has to get way more technical. 

BY GUY SELA 


The rapid growth rate of world’s population presents tremendous 

challenges for humanity, the biggest of which is how 

to sustainably feed the world. The Food and Agriculture 

Organization of the United Nations estimates that agricultural 

production will have to increase by around 60 per cent by 2050 to 

feed the planet. To meet this challenge, however, the way we do 

agriculture must change substantially. Farming has to optimize, 

and to do that, it must get more technical. 

As always, farmers deal with many uncertainties and risks like 

weather changes, input prices, incidence of pests and disease, 

equipment failures, and fluctuations in market prices on a daily 

basis. They also have to make significant decisions each day. 

However, these decisions can be a risk themselves because most 

farmers cannot accurately predict what impact they will have on 

the resulting crop yields. 

So, to minimize the risks involved in farming, farmers must 

make better-informed decisions. In order to make better-informed 

decisions, farmers must efficiently control the management practices 

that are in their hands. This depends on accurate data analysis. 

Precise Fertilization 

The precise use of fertilizers 

contributes to an increase in 

crop yields more than any 

other technique. However, 

to maximize crop yields 

and prevent nutrient losses 

to soil, water, and air, 

fertilizers must be applied 

more efficiently. Currently, 

the misuse of fertilizers is a 

global phenomenon due to 

the complexity of finding the 

optimal fertilization range. 

Many farmers still rely on 

trial and error, guesswork, 

and estimation. The result is 

crops that do not meet their 

yield potential, and increased 

environmental pollution. 

Knowing the exact fertilizer 

rate is a science and requires a 

thorough analysis of multiple 

factors. In fact, farmers often 

have to consider hundreds 

of dynamic parameters, such 

as crop nutrient uptake rates, 

research data, soil chemicals, 

physical and biological 

properties, weather, water 

composition, soil testing 

methods, irrigation techniques, 

fertilizer characteristics, 

and interactions between 

fertilizers. Processing these 

large data sets to continuously 

return sustainable fertilizer 

recommendations requires 

skills, vast knowledge, and 

access to agricultural research 

and databases. 

However, research results 

and scientific publications are 

often not readily available 

to farmers. When they are 

available, data is often difficult 

to read, partial (for instance, it 

refers to only one nutrient), or 

does not fit the farmer’s specific 

field conditions. What’s more, 

research data is often not 

consistent. Data obtained from 

one research paper is different 

than the data obtained from 

another. As such, an enormous 

amount of research results 

and data must be compared 

and analyzed to obtain a 

reliable knowledge base. 

Evidently, without precision 

ag technologies, this is an 

impossible task. 

The Technological 

Revolution of Big Data 

Big data analytics of agricultural 

research results and 

actual, historical field data 

creates a continuously updated, 

reliable knowledgebase. This 

can revolutionize the way 

farmers make daily decisions. 

It can help farmers sustainably 

increase crop yields, save 

money and time, and make the 

right decision time after time. 

To take advantage of this data 

revolution, however, farmers 

need to have direct access to 

cloud-based decision-making 

tools. These translate the huge 

amounts of data and analytics 

“ 

The Food and Agriculture Organization 

of the United Nations estimates that 

agricultural production will have 

to increase by around 60 per cent by 

2050 to feed the planet." 

into best practices and actionable 

information. Thankfully, in 

contrast to most other tools in 

agriculture, software algorithms 

and data analytics do not require 

any hardware installation. 

Ideally, they should easily 

integrate with any external 

source of data, such as sensors, 

drones, and machinery. 

Fertilizer optimization, based on 

big data analytics, help farmers 

maximize crop yields in the most 

efficient and economical way. 

Not only does the farmer get 

access to an easy-to-use interface 

that eliminates the guesswork 

and minimizes the uncertainties 

involved in making fertilizer 

management decisions, but the 

software also provides projections, 

alerts and reports. It’s just 

a bonus that the software works 

on any device, including laptops, 

smart phones, and tablets. 

Guy Sela is a plant nutrition expert and the CEO 

of SMART! Fertilizer Management, which makes 

an innovative software for fertilizer optimization. 

The software provides optimized and fast fertilizer 

recommendations and helps growers dramatically 

increase their crop yields and save costs.

KELZYME's business development manager, show off their leading hydroponics product. 

NUTRITION FOR 

AGRICULTURE: 

With KELZYME®, organic and non-organic growers find an easy-to-use, 

no-fuss nutrient solution to use in their hydroponic and traditional 

systems. Brad Klock, vice-president of sales and marketing, explains 

more about the formula behind the company’s flagship calcium-rich 

mineral composite product and how it benefits indoor-grown plants.

Years in business 

From its business office in Brooklyn, 

New York, and its operations facility 

in Nevada, the makers of KELZYME 

products research, perfect, and market 

all-natural fertilizers, plant nutrients, 

and soil amendments and conditioners. 

The products are entirely sourced from 

a unique mineral deposit that can only 

be found in northern Nevada, where 

ancient sea beds once lay. 

The KELZYME Research & Development 

Center is where the magic behind 

element XX TM —a unique hydroponic, 

soil, and soilless media plant fertilizer— 

takes place. “The business has evolved 

from a mining company to one now 

focused on bringing the benefits of the 

material to individual growers right up 

to and including commercial ag,” shares 

Brad Klock, KELZYME’s vice-president of 

sales and marketing. 

With the identification and confirmation 

of a unique mineral deposit having 

taken place by the mining experts, the 

company is looking forward to an exciting 

future in the horticultural industry 

as it takes its formulas to the next level. 

“ 

The business has evolved 

from a mining company 

to one now focused on 

bringing the benefits of 

the material to individual 

growers right up to and 

including commercial ag.” 


“Sales, distribution, and marketing are 

now our go-to market priorities,” says 

Klock. “We have certified our products 

and remain a manufacturing company 

also dedicated to operational efficiencies 

and safety.” 

KELZYME manufactures multiple 

lines of products geared for the indoor 

gardening market, traditional home 

and garden application, and commercial 

agriculture. The products are 

naturally occurring mineral composites, 

available currently in two grades: 

granular and micronized. “The micronized 

product is offered for hydroponic, 

aquaponic, or irrigation systems, but 

it is also an outstanding option for 

use as a dry application in soil and 

other growing media,” explains Steve 

Swallow, KELZYME’s business development 

manager, adding that the granular 

alternative is designed for soil 

and soilless media and provides for 

residual activity. For the indoor garden 

market, materials are sold under the 

element XX name, while traditional 

home and garden and commercial 

product offerings are both sold under 

the 100% Natural CAFE TM name. 

All KELZYME products are singlesourced 

from a specific location in 

northern Nevada, an area the Western 

Interior Seaway covered more than 

1 million years ago. “This unique 

product and related chemical profile is 

only available from the existing site,” 

says Klock. The chemical composition 

is highlighted by calcium and iron. It 

also includes such macronutrients as 

magnesium and sulfur, and contains 

such micronutrients as chlorine, 

manganese, zinc, boron, copper, and 

molybdenum in addition to other plantbeneficial 

elements and compounds 

such as silicon and carbon. 

Dave Newton 

Of all these nutrients, Klock believes 

calcium to be the most important for 

plants. “Plants require a panel of essential 

elements in the root zone. One of the 

most critical to plant development, and 

also one required in the largest quantity, 

is calcium,” he says. “A calcium 

deficiency may often result in poor root 

and shoot growth, necrosis on leaves, 

and abnormal development of growing 

points or terminal buds.” 

The good news for growers is that 

KELZYME products contain a guaranteed 

minimum of 35 per cent calcium. 

“Calcium enhances plant root and shoot 

growth; it is an integral part of plant cell 

wall structure and builds strong stems 

and leaves. As calcium is not easily 

redeployed from one area of a plant 

to another, a steady supply of calcium 

is necessary throughout the life of a 

plant to strengthen its vascular system, 

produce thicker and stronger stems, 

and promote new growth at the growing 

tips,” explains Klock. 

In addition to its impressive mineral 

content, KELZYME products boast 

other exceptional qualities as well. 

For instance, they are all OMRIlisted 

and CDFA Organic Input 

Material (OIM)-registered. KELZYME 

products are all-natural, easy to use, 

environmentally responsible, and 

effective in various applications and for 

all plants. Among the products, Dave 

Newton, KELZYME’s northern California 

account manager, says element XX has 

been the one to really take off as a new, 

easy-to-use and effective product for 

organic indoor and outdoor growers. 

“Within the element XX product line, the 

granular and micronized options are 

seeing roughly equal use,” he says. 

KELZYME products are currently available 

through various retailers, notably 

in the California and Nevada markets. 

The company has partnered with select 

“ We have certified our 

products and remain a 

manufacturing company 

also dedicated to 

operational efficiencies 

and safety.” 

distributors and also sells online through 

its own website as well as other various 

online vendors. The company is seeing 

more interest from larger distributors 

as well and are currently expanding 

geographically, with a focus on 

Washington, Oregon, and Colorado. 

Along with building its distribution 

network, KELZYME Research & 

Development is currently undergoing an 

expansion at its manufacturing site to 

include additional processing and packaging 

equipment, together with a new 

building and warehouse. 

KELZYME also expects to expand its 

product offerings. The team is currently 

evaluating complementary products 

that will include coco coir and molasses 

products/blends (together with 

element XX), and expanding their use 

as an ingredient in various soil blends 

sold by other companies. They are also 

testing finer particle sizes as well as 

specialty natural products with unique 

surfactant properties to provide for 

faster nutrient response times, especially 

in hydroponic applications. 

All in all, the modern growing industry 

should expect exciting innovations from 

KELZYME Research & Development in 

the near future.

DRYGAIR 

ENERGIES LTD. 

Making your 

greenhouse greener 

Traditional methods of reducing humidity open up a greenhouse to the influences of external conditions 

that can negatively affect a crop. Israel’s DryGair, however, believes it has the solution to this problem.

Years in business 

DryGair takes humidity seriously. 

So seriously, in fact, that the Israeli 

dehumidifier company hopes its products 

will solve the issues created by 

heat and ventilation—the traditional 

methods of reducing humidity in a 

greenhouse—entirely. 

“If you have a good solution that 

you and your team believe in, 

you can educate the market and 

make it happen,” says Yonatan 

Peretz, who works with DryGair in 

marketing and sales. 

Instead of relying on vents opened to 

the outside world, DryGair units work 

within a “closed and isolated” growing 

environment. They remove water from 

the air to keep humidity at optimal 

levels, all without any influence from 

external conditions. 

By keeping the greenhouse sealed, 

DryGair technology enables growers to 

more easily maintain uniform conditions. 

This leads to improved energy efficiency, 

less pesticide use, better yields, and 

plenty of financial savings, Peretz says. 

The company’s first product—a dehumidifier 

that can manage 500-4,000 square 

meters worth of plants, depending on 

the crop—was developed in 2010 by the 

DryGair team in collaboration with Dr. 

Avraham Arbel of Isreal’s Agricultural 

Research Organization, Volcani Center. It 

was Dr. Arbel who first came up with the 

concept as part of his PhD thesis. 

Even before it was available, the unit 

piqued client interest. “Our first customer 

was a grower who understood humidity 

problems and came to hear about our 

prototype,” says Peretz. 


The grower placed his plants in 

DryGair’s experimental greenhouses, 

sprayed them with water and left them 

overnight. The next day, he came back 

to find the plants dry and with healthy 

leaves. “He immediately wanted to buy 

the first unit, although it was still at a 

prototype stage,” Peretz says. 

Since then, DryGair has developed 

several dehumidifiers to tackle the 

needs of diverse greenhouse designs, 

crops, growing methods, and climate 

conditions around the world. Of course, 

the company tested these products in 

real-life trials in different countries with 

various crops to make sure they would 

deliver exactly what its end-clients 

wanted. “Our end-customers are the 

plants, and their needs are our top 

priority,” explains Peretz, who adds that 

healthy plants lead to happy growers. 

And so far, DryGair has helped 

create many a happy plant and 

grower. One gardener contacted 

DryGair to tell the company 

“he saved 15 per cent of his 

crop” after using one of its 

units. Also, the company 

says growers on average 

reduced their energy 

usage by 50 per cent. 

Today, the company 

sells its units in Israel, 

Holland, Germany, UK, 

Norway, Denmark, the 

US, and Vietnam, with 

plans to expand. And 

there’s no doubt the 

company can reach 

its goal. It’s already 

capitalized on its 

strengths of innovation 

and efficiency, 

sustainability, 

flexibility, and team 

work to expand 

from a three-person 

company in Israel to an 

international exporter 

that employs 10 people. 

“Our employees 

believe in our solution 

and therefore they are 

dedicated,” says Peretz. 

“We have professional 

conferences to deepen our 

agriculture understanding and 

we try to widen our horizons by 

introducing interesting issues during 

our weekly team meetings, during 

mutual breakfasts.” 

“ 

If you have a good solution that 

you and your team believe in, you can 

educate the market and make it happen.”

10 facts on... by Philip McIntosh 

TURN UP THE 

BASE? 

There are acids and there are bases. And then, of course, there are salts. 

Let’s talk about bases this time.

BASES COUNTERACT the properties and behaviors 

of acids. If you split a water molecule just right, you get a 

hydronium ion (H + ) and a hydroxide ion (OH - ). 

IT’S THE RATIO of H + to OH - that determines the 

acidity or basicity of a solution. More OH - makes it a base. 

BASES ALSO REACT with fats and oils, 

which is why lye (NaOH or, historically, 

KOH) is added to tallow to make a 

simple kind of soap. 

BASIC SOLUTIONS are not created by 

splitting up water molecules. Basic solutions 

are made by the dissolution of a substance 

that releases free hydroxide ions. 

LIKE ACIDS, 

bases are 

characterized by 

their pH value—the 

negative logarithm of 

the H + concentration. 

A solution with a 

pH greater than 7 

has more free OH - 

ions, which is what 

makes it basic. 

UNLIKE 

ACIDS, 

which tend 

to be sticky, 

sour-tasting, 

and have a 

strong smell, 

bases tend to 

be slippery and 

bitter-tasting, 

with little odor. 

WAIT A MINUTE! Ammonia? Yes, Ammonia 

has a strong affinity for an additional proton (H + ), 

so when it’s added to water it rips one off a water 

molecule to produce NH 4 

+ 

and OH - in solution. 

COMMON SOURCES 

of hydroxide ions include 

sodium hydroxide (NaOH), 

potassium hydroxide (KOH), 

and ammonia (NH 3). 

PEOPLE TEND to fear acids, but bases can be 

dangerous, too. A strong solution of NaOH is used 

to dissolve flesh off of bone. Don’t get any on you.
